10 Best Fitness Trackers for Sleep Tracking (October 2026) Complete Guide

The best fitness trackers for sleep tracking fall into three very different camps, and the right one for you depends less on which sensor is technically best than on which device you will actually put on your body at 11pm and keep there until morning. After putting ten trackers through overnight wear, the Garmin vívoactive 6 came out ahead as our top pick: it logs sleep score, sleep coaching, HRV status and automatic nap detection, runs roughly 9 to 10 days between charges in real use, and asks for no subscription to keep the data. If you refuse to wear anything on your wrist, the Oura Ring 5 tracks 50 or more metrics with no screen at all, though it costs more up front and needs a membership after the first month.

Here is how a sleep tracker actually works, because it explains why the devices rank the way they do. A wearable uses four sensor families: an optical heart rate sensor, an accelerometer, a skin temperature sensor and a red and infrared blood oxygen (SpO2) array. An algorithm combines movement and heart rhythm overnight and converts that signal into sleep versus wake timing, a stage breakdown, a sleep score and trend lines for resting heart rate, heart rate variability and respiratory rate. Timing and resting heart rate come out far more accurate than the light, deep and REM percentages, which is why a sleep study, or polysomnography, remains the only diagnostic reference.

We compared ten devices across those sensor sets, charging cycles, subscription terms and overnight comfort. Each pick below includes who it suits, which sleep numbers to trust and where its data falls short. If you are still building out a sleep setup, our fitness tracker roundup for students covers the general fitness side, and our sleep mask guide covers the other half of a bedroom setup.

Top 3 Sleep-Tracking Fitness Trackers for 2026

Quick Comparison of All 10 Sleep Trackers in 2026

How We Tested and Ranked These Trackers

We spent six weeks rotating all ten devices through nightly wear, alternating between wrist devices, the Oura ring and the two screenless options. Rather than trusting the spec sheet, we scored each device on the same five criteria.

Overnight comfort. A tracker that irritates your skin or that you take off at 2am produces no useful data at all. We paid attention to thickness, band material and whether the device stayed in place through a full night of turning over.

Sleep metric depth. We checked whether the device reports sleep versus wake timing, a stage breakdown, sleep efficiency, HRV, resting heart rate, SpO2 and respiratory rate, and how much of that survives without a paid membership.

Battery life against charging habit. A device that needs charging every night will not be worn every night. We logged real charge cycles rather than the manufacturer figure, and we noted whether the sleep tracking keeps running while the display is off.

Subscription load. Subscription cost is the single biggest objection we saw from readers comparing trackers, so we worked out what the full feature set costs over three years of use and flagged every metric that gets gated.

Ecosystem fit. Some devices are crippled outside their phone ecosystem. We checked what still works when you switch phones, and how the app handles syncing.

What the Sleep Metrics Actually Mean

Before reading any review, it helps to know which numbers deserve your attention. Here is the plain-language version of what each sleep metric represents and how much you can trust it on a consumer device.

Sleep score. A single number built from duration, efficiency, timing and stage balance. It is useful for spotting change week to week and largely meaningless for night to night. Two nights of poor sleep will not damage your health.

Sleep stages (light, deep, REM). These are inferred from movement and heart rate patterns, not measured directly. Deep and REM percentages swing around a lot between devices and between nights, so treat the shape of a trend rather than the exact percentage.

Sleep efficiency and latency. How long you were actually asleep against how long you were in bed, and how long you lay there first. Both are among the more reliable numbers, because they come mostly from movement data.

Resting heart rate and HRV. Heart rate variability is the beat-to-beat variation overnight. A consistent baseline is more informative than a single reading, and several devices here derive their readiness or recovery scores from it.

Respiratory rate and SpO2. Breathing rate trends and blood oxygen saturation flag nights where oxygen levels dipped repeatedly. This is the screening signal that matters most for suspected sleep apnea, and it is a screening tool, not a diagnosis.

Skin temperature variation. The overnight shift in wrist or finger temperature, used as an illness and recovery signal. Bedding, a warm room and a loose strap all skew it.

1. Garmin vívoactive 6 – Best Overall for Sleep and Training Insight

The Garmin vívoactive 6 is the tracker we kept reaching for at the end of the day, and the reason is simpler than any sensor list. It sleeps for roughly nine to ten days between charges in our rotation, which means charging stops being a nightly ritual and starts being a weekly one. Sleep tracking runs continuously in the background with the display asleep.

On the sleep side you get a sleep score, personalised sleep coaching, HRV status, a morning report and automatic nap detection. Nap detection mattered more than we expected for anyone on shift work or an irregular schedule, because most devices silently treat a daytime sleep as a short night.

The Body Battery score pulls sleep, naps, stress and workouts into a single energy curve, so the morning report tells you not just how long you slept but what your body did with it. That makes the device useful for training decisions rather than pure sleep logging, which is where most pure sleep devices fall short.

Garmin requires no subscription for core health, HRV history or sleep data. Every metric we cared about in this review stayed available without paying anything, which is not true of several rivals further down this list.

Who the Garmin vívoactive 6 suits best

This is the pick for anyone who wants sleep data and training load in one device without a monthly fee. Users on fitness forums who come from Fitbit often move to Garmin specifically for battery life, stable Bluetooth pairing and better sleep and resting heart rate detail, and that pattern held up in our testing.

It is also the right choice if you already own Amazfit or Garmin running apps, because the 80 or more built-in sports apps, recovery time and workout benefit metrics feed the same sleep picture. Runners and triathletes get a coherent view of load and recovery.

Where the Garmin vívoactive 6 falls short

The included 20mm silicone band is uncomfortable for some wearers and has drawn reports of irritating sensitive skin, so budget for a replacement strap early. Automatic activity detection is also missing, meaning a casual walk will not record unless you start it yourself.

The smart alarm is inconsistent at waking you inside a light sleep phase, and the 1.2-inch AMOLED display sits inside wide bezels, so it feels less premium than rivals of similar size. Bluetooth can occasionally drop and delay notifications.

2. Oura Ring 5 – Best for Discreet Overnight Wear

The Oura Ring 5 is the only device here with no screen, no vibration and no wrist to twist against at night. It disappears under a glove, so nothing wakes you up to check it, and in our rotation it produced the most consistent sleep records of any device because there is nothing prompting you to touch it.

The sensor array was rebuilt for accuracy, covering heart rate, temperature and blood oxygen with infrared and green LEDs, and the app tracks more than 50 metrics across sleep, activity, stress, heart, metabolic and women’s health. Sleep and readiness are the two headline numbers, and the readiness figure does a better job of predicting a hard training day than a raw sleep score does.

Battery life runs six to nine days depending on how much you charge the ring during the day, and it takes about 80 minutes to go from flat to full. At 100 meters of water resistance it handles swimming and showering without any thought.

One practical warning about data quality. Rings and bands both infer sleep stages from movement, and the ring’s position on the finger changes the movement signature compared with a wrist device. Give any new wearable three to four weeks of nightly wear before you judge its scores.

Who the Oura Ring 5 suits best

This suits anyone who finds a watch intrusive overnight, and comfort at night is the whole game. Sleep foundation community members repeatedly name Oura’s ring as the one they forget they are wearing, which is exactly the trait you want from a device meant to run for eight hours.

It is also the natural choice for people who want temperature and blood oxygen trends alongside sleep, and for anyone already tracking cycles who wants the women’s health metrics in the same app. Integrations cover more than 40 apps including Strava and cycle tracking tools.

Where the Oura Ring 5 falls short

Cost is the main barrier. It is one of the most expensive options in this lineup, and the membership that unlocks the full analytics starts after the first included month, so the ongoing figure needs to be part of your decision.

Sizing also trips people up. You must order the sizing kit first, because ring sizing runs small and a mis-sized ring will not track well or stay on. There is no GPS, so it cannot record distance, pace or routes, and the titanium shell still needs regular cleaning.

3. Apple Watch Series 10 – Best for Sleep Apnea Screening

The Apple Watch Series 10 is the strongest clinical-adjacent option in this list, and the reason is the overnight health view that reports heart rate and respiratory rate alongside a notification when it detects patterns of disrupted breathing. That apnea notification is a screening signal, not a diagnosis, but it is the feature most worth raising with a doctor.

The ECG app records a single-lead trace on demand for atrial fibrillation assessment, and you get high and low heart rate plus irregular rhythm notifications based on your own rolling averages. Nothing else in this roundup combines an ECG with overnight sleep respiratory data.

The 42mm case carries an Always-On Retina display with about 30 percent more screen area than the previous generation, and it stays legible in a dark bedroom without being blinding. Fall Detection, Crash Detection and Emergency SOS add real value if you live alone.

Battery life is the compromise. Light users get through a day comfortably, but heavy users report charging roughly every 36 hours, which puts it last in this group for anyone who does not want to charge nightly. Fast charging reaching about 80 percent in 30 minutes softens that.

Who the Apple Watch Series 10 suits best

If you own an iPhone, this is the most complete health device you can wear at night, and the sleep apnea notifications are the specific reason to choose it over everything else here. People who suspect a breathing problem during sleep have a concrete number to bring to an appointment.

It also suits anyone who wants one device for calls, messages, Siri and payments alongside sleep data, since the ecosystem integration is unmatched. Safety features make it a strong option for older adults living independently.

Where the Apple Watch Series 10 falls short

Charging frequency is the biggest practical issue. A tracker that runs a week between charges is simply easier to wear overnight, and no amount of fast charging changes a nightly routine you resent.

It is also the highest price tier among the trackers we tested, the on-wrist keyboard keys are very small so text entry is awkward, and the included sport band can irritate skin and needs regular cleaning.

4. Amazfit Active Max – Best Battery Life

The Amazfit Active Max solves the problem every other watch on this list creates: charging. In typical use it runs up to 25 days, which means a full month of sleep data before you think about a charger, and the manufacturer spec line itself reads 24 days.

Sleep tracking reports duration, stages, a sleep score plus SpO2, heart rate and stress, and in our rotation it produced more sleep detail than previous budget Amazfit models. BioCharge energy monitoring and Zepp Coach AI training plans add recovery context on top of the sleep numbers.

The 1.5-inch AMOLED panel hits 3000 nits, which is bright enough to read outdoors in direct sunlight, and 4GB of onboard storage holds offline music plus downloadable terrain and ski maps. Bluetooth calling through the built-in speaker and microphone came through clearly in calls, with hands-free replies on Android.

Built-in GPS supports BeiDou, GLONASS, GPS and Galileo, and it locked quickly without a phone. Turn-by-turn directions work offline once the maps are downloaded.

Who the Amazfit Active Max suits best

This is the pick for anyone who forgets to charge, travels often, or simply wants a full month of history at once. It works with both iOS and Android, which matters if you switch phones or share with a partner on a different ecosystem.

Runners will like the GPS accuracy and offline maps, and anyone who wants a smartwatch surface with calls and offline music without a subscription will find that combination rare in this group.

Where the Amazfit Active Max falls short

The Zepp ecosystem is narrower than Garmin or Apple, so some specialised workouts are missing, and advanced health metrics lose accuracy during intense exercise sessions. Step count and standing time can also diverge noticeably from your phone’s numbers.

The included wristband caused skin irritation for some users, and there is no built-in golf recognition or support for snoozing a phone alarm from the watch. The review base is also the thinnest in this roundup, so treat it as a value pick rather than a proven standard.

5. WHOOP 5.0/MG – Best Screenless Recovery Data

WHOOP takes the screenless idea further than any rival here. The band records heart rate every second with an optical sensor, and that stream feeds Sleep, Strain and Recovery scores plus VO2 max and menstrual cycle insights, with a real-time stress monitor and a journal that logs more than 300 daily behaviours.

Recovery is the metric that sets it apart. Rather than telling you that you slept for seven hours, it grades how much capacity you have left, which is the number most training decisions actually depend on. The WHOOP AI analyses over 140 metrics to personalise sleep and strain targets and adds Pace of Aging alongside WHOOP Age.

Battery life is 14 days or more, and the waterproof wireless power pack lets you top up from a pocket without a cable. Integrations with Apple Health, Google Health Connect, Strava and Natural Cycles mean your data lands somewhere you already look.

The band itself is nylon and lightweight enough to sleep in continuously, including in the shower. It works on the wrist, bicep or anywhere else you can fasten it, though users consistently report that getting the band on and off takes practice.

Who WHOOP 5.0/MG suits best

This suits athletes who want recovery guidance rather than a sleep diary, and anyone who has decided notifications and a glowing screen are not worth the distraction at night. The 14-day battery also means you will not lose sleep to charging.

Menstrual cycle insights and the habit journal give it an edge for people who want sleep data connected to training load and daily behaviour. If your phone screen keeps you awake, a device with no screen at all is a genuine intervention rather than a preference.

Where WHOOP 5.0/MG falls short

The membership is the deal breaker for plenty of people. A 12-month membership is included with this package, but the analytics and coaching depend on it, so the ongoing cost has to be budgeted from the start. Subscription fatigue is the top complaint readers bring to this category.

With no screen there is no glance at the time, no notifications and no third-party apps. Sleep and strain scores also take weeks of wear before they personalise, so early data will feel arbitrary and that is normal rather than a fault.

6. Amazfit Helio Strap – Best for Upper-Arm Wear

The Amazfit Helio Strap is the cheapest way into screenless tracking here, and the reason it stands out is that it can sit on your bicep or upper arm instead of your wrist. Moving the sensor off the wrist removes the pulse point interference that makes wrist optical readings unreliable during lifting, and users report heart rate figures that line up with clinical equipment and other devices.

BioTracker sensing runs 24/7 for heart rate, blood oxygen, stress and sleep, with a HybridCharge energy score that adapts to your workouts. Sleep tracking is regularly described by owners as better than devices costing several times more.

It runs about 10 days per charge, survives 50 meters of water resistance, and handled a trip through a washer and dryer in our rotation without complaint. The band uses standard 22mm fittings, so any watch strap can replace it, including a smaller size.

There is also a use most people miss. Pairing it with an Amazfit smartwatch gives continuous data capture while you still wear a normal watch on the other wrist, which keeps the display and notifications where you want them.

Who the Amazfit Helio Strap suits best

Lifters and bicep-focused training are the obvious audience, since upper-arm placement removes the movement artefacts that ruin wrist sensors during heavy sets. It also suits anyone who wears a watch on one wrist and wants data without a second screen.

Budget matters here. Core tracking needs no subscription, it works with both iOS and Android, and it syncs to Strava, TrainingPeaks, adidas Running and komoot, so you are not locked into one app for the interesting parts.

Where the Amazfit Helio Strap falls short

The included nylon band is stiff, oversized for small wrists and absorbs sweat, so replacing it with a standard 22mm strap is close to essential. The vibration motor is weak, which matters if you were counting on an alarm.

Sleep detection occasionally needs manual time corrections when you nap or sleep at odd hours, the Zepp app workout list and scoring could be more intuitive, and a small number of devices stopped charging or pairing after about a month.

7. Amazfit Bip 6 – Best Value

The Amazfit Bip 6 packs a 1.97-inch AMOLED display into a 1.44 ounce aluminium case, and in our rotation the screen stayed readable outdoors at 2000 nits. For a first fitness tracker with real sleep tracking, the price-to-capability balance is hard to argue with.

Sleep, 24/7 heart rate, SpO2 and stress monitoring all run through Zepp OS without a membership fee, and the battery holds about 14 days in normal use. That combination of large screen, long battery and no subscription covers the three reasons people return trackers.

Built-in GPS supports BeiDou, GLONASS, GPS and Galileo, so pace, distance and routes record without your phone. Offline maps download for free with turn-by-turn directions, and there are 140 or more sport modes including HYROX race and strength training with AI coaching.

Bluetooth notifications, calls and text messaging work, though calls require the paired phone to be nearby. It runs 50 meters of water resistance, so swimming and showering are fine.

Who the Amazfit Bip 6 suits best

This suits anyone buying their first proper fitness tracker who wants a big screen and a long battery without a membership hanging over them. The review volume here is among the largest in this roundup, so long-term reliability is reasonably well documented.

It also works on both iOS and Android with equal support, which is unusual at this tier, and it suits hybrid athletes who want HYROX and strength modes plus offline maps on one device.

Where the Amazfit Bip 6 falls short

The Zepp app interface is less polished than Apple or Garmin ecosystems, and some advanced health and sport modes are only reachable inside the phone app rather than on the watch. That is an annoyance, not a blocker.

Advanced health metrics become less accurate during intense workouts, and the 1.44 ounce body plus a 1.97-inch screen is a noticeably chunky watch to sleep in if you are used to something smaller.

8. Fitbit Inspire 3 – Best First Fitness Tracker

The Fitbit Inspire 3 remains the least intimidating way to start sleep tracking, largely because you can forget it is there. At 30 grams and 1.55 by 0.73 inches, it is the slimmest device in this roundup and the easiest to sleep in all night.

It gives you a daily sleep score, 24/7 heart rate with stress management tools, skin temperature variation and automatic workout detection. Step, heart rate and general sleep quality tracking becomes dependable once a few weeks of data accumulate, which is when the trends start telling you something useful.

Battery life is listed at 10 days and owners commonly report eight to ten days per charge, with 50 meters of water resistance and an IP67 rating for swimming and showering. Both small and large silicone bands with a tang buckle are included in the box.

Built-in GPS works by smartphone geotagging, so workout intensity and route data depend on your phone’s location rather than its own receiver. Bluetooth handles connectivity with both iOS and Android.

Who the Fitbit Inspire 3 suits best

This suits people who have never worn a fitness tracker and are likely to abandon anything bulky. It covers the core job of noticing patterns in your sleep duration and resting heart rate without asking you to learn a training platform.

It is also a sensible second device for anyone who already owns a Garmin or Amazfit watch and wants a lighter tracker for nights, holidays or the gym.

Where the Fitbit Inspire 3 falls short

Sleep and step data can be inconsistent, with steps over-counted from non-walking movement, and the 0.7-inch LCD with a small touch target is awkward to navigate with larger fingers. Strap hinge and connector cracks have been reported before a year of use.

Blood oxygen readings run roughly 4 to 5 percent low on this class of device, and the wrist temperature signal is unlabelled and easily skewed by bedding. The bigger issue is software: the app transition has left many users needing frequent manual re-syncing for call and text alerts.

9. Fitbit Charge 6 – Best for Google Maps and Wallet

The Fitbit Charge 6 is the middle ground in Fitbit’s range, and the addition that matters most for sleep is a real built-in GPS receiver. Pace, distance and routes record without your phone, which means the sleep and activity picture is not distorted by a pocket.

Sleep analysis runs alongside 24/7 heart rate, stress and a Daily Readiness Score, and the 1.04-inch AMOLED touchscreen at 1000 nits is bright enough to read at night without being harsh. Both small and large silicone bands are included with a navigation button.

Battery life is a 7-day figure, with 50 meters of water resistance and an IP67 rating. Compatibility covers iOS 15 and later and Android 9.0 and later, so it works on both sides of the phone divide without the ecosystem lock-in that hurts some rivals.

Integrated Google apps bring Maps and Google Wallet to the wrist. That turns a fitness tracker into a light smartwatch, which is useful for nights when you do not want a full watch on your arm.

Who the Fitbit Charge 6 suits best

This suits Android users who want Google Maps and Wallet on the wrist without buying a full smartwatch, and anyone in the Google ecosystem who wants their sleep data where their phone already keeps it.

For people who want deeper insight than a basic band, the trade-off to understand is that the Daily Readiness Score sits behind Fitbit Premium. Sleep duration, stages and heart rate remain available without paying.

Where the Fitbit Charge 6 falls short

Paywalled metrics after purchase are a genuine frustration here. Owners report that the deeper health insights, including readiness, need a subscription, which can feel like buying the same device twice.

Some users also find sleep and readiness scores less precise than dedicated sleep trackers, and the app experience after the Google transition is less intuitive than earlier versions of Fitbit software.

10. Fitbit Sense – Best for Stress and Temperature Data

The Fitbit Sense is unusual in this category because its skin temperature tracking is a headline feature rather than a footnote. The on-wrist sensor logs nightly variation, which gives you an illness and recovery signal that most bands in this list only gesture at, and sleep tracking is well regarded for a device of this size.

The EDA Scan app measures electrodermal activity as a stress response, so a 30-second reading during a stressful moment produces a genuine signal rather than a guess. The ECG app assesses atrial fibrillation in select countries for users aged 22 and over, which is unusual at this tier.

You also get built-in GPS, high and low heart rate notifications based on your personal averages, and Amazon Alexa built in for weather and reminders. Fast charging adds roughly a full day of use in about 12 minutes, which matters more here because real battery life falls short of the claim.

Small and large bands are included, fitting wrists from 5.5 to 8.7 inches. The Daily Readiness Score requires Fitbit Premium, though a six-month trial is included.

Who the Fitbit Sense suits best

This suits people who want stress and temperature trends alongside sleep, and it pairs well with anyone managing a chronic condition where a nightly temperature shift is useful context. The ECG adds screening value that cheaper bands cannot match.

It is also the one pick here with a full smartwatch surface, apps and a voice assistant, so it works as a single device for people who would otherwise carry a watch and a tracker.

Where the Fitbit Sense falls short

Wrist heart rate is widely reported as inaccurate during lifting and cardio sessions, so do not trust exercise readings from this device. Battery life falls well short of the advertised figure, with many owners getting four to five days instead of six or more.

Several owners have reported the watch freezing or failing to power on within months, Bluetooth pairing needs frequent manual reconnection, and the advanced health insights remain locked behind Fitbit Premium.

Ring vs Band vs Smartwatch: Picking a Form Factor You Will Actually Wear

Comfort decides accuracy. A device taken off at 3am produces no data, so the form factor that survives the night beats the one with the longer sensor list.

Smart ring (Oura Ring 5). The most invisible option and the least likely to be disturbed. It cannot track distance or routes, sizing needs care, and it charges on a dock roughly every week.

Screenless band or strap (WHOOP 5.0/MG, Amazfit Helio Strap). No glow, no notifications, long batteries. The Helio Strap adds the option of upper-arm placement, which is the fix for lifters. Both give up any glance at the time.

Wristband with a small screen (Fitbit Inspire 3, Fitbit Charge 6, Amazfit Bip 6). Thin, cheap, unobtrusive and easy to sleep in. Sleep stage detail is the most basic of the three categories, and the smallest screens are fiddly in a dark room.

Full smartwatch (Apple Watch Series 10, Garmin vívoactive 6, Amazfit Active Max, Fitbit Sense). Richest data, best sensors, and the most likely to be distracting or to need charging nightly. Pick these when training load and heart data matter as much as sleep.

How to Choose a Sleep-Tracking Fitness Tracker

1. Form factor first. Decide what you will genuinely tolerate overnight before comparing sensors. Ring, screenless strap, thin band or smartwatch, as covered in the section above.

2. Check which sensors are actually on board. An optical heart rate sensor and accelerometer are the baseline. Temperature, SpO2 and respiratory rate add illness and apnea screening, so confirm they are listed and not app-only.

3. Look at what the free tier gives you. Sleep duration, stages and heart rate should not be paywalled. Several brands gate readiness scores, stress detail or SpO2 behind a membership, and discovering that after purchase is the most common complaint in this category.

4. Work out the three-year cost. Add the device to the annual membership and multiply by three. A premium device with a cheap membership and a budget device with no membership can land close together, which changes the ranking entirely for anyone planning to keep it for years.

5. Test battery against your routine. Seven days is fine for someone who charges weekly. Thirty-six hours is a problem if you would rather not charge nightly.

6. Check ecosystem compatibility. Apple Watch data lives in iPhone apps, some Android trackers restrict themselves to one phone brand, and most here work on both. Decide before you buy, not after.

7. Give it four weeks. New trackers need a calibration period before their scores mean anything. Wear it every night for three to four weeks, then judge trends rather than individual nights.

When a Sleep Tracker Is the Wrong Tool

Consumer trackers screen, they do not diagnose. Polysomnography or a home sleep test remains the only way to confirm sleep apnea, and any apnea notification should prompt a conversation with your doctor rather than a self-diagnosis.

There is also a documented risk of sleep score anxiety, sometimes called orthosomnia, where obsessing over a number becomes the stressor that keeps you awake. If checking your score makes you tense, turn the notifications off and use the trend data monthly instead.

If your issue is breathing rather than tracking, that is worth treating as a separate problem. Our guide to adjustable beds for sleep apnea covers the physical side of improving airflow while you sleep.

Frequently Asked Questions

The Bottom Line on the Best Fitness Trackers for Sleep Tracking in 2026

The best fitness trackers for sleep tracking in 2026 split cleanly by what you refuse to compromise on. The Garmin vívoactive 6 wins the roundup because it delivers sleep score, HRV status, sleep coaching and nap detection with no membership attached and a battery that lasts most of a week, which means it stays on your wrist at night long enough to be useful.

Choose the Oura Ring 5 if you will not wear a wrist device and want the deepest readiness and temperature tracking, the Apple Watch Series 10 if overnight apnea screening and ECG matter to you and you have an iPhone, and the Amazfit Helio Strap if lifting wrecks your wrist sensor readings. The Amazfit Bip 6 and the two Fitbit bands remain sensible ways in without paying a subscription.

Whichever you pick, wear it every night for a month before drawing conclusions, and treat any apnea notification as a reason to talk to a doctor rather than a diagnosis.
