IdeaStorm is a free iPad app for quickly creating sketches and diagrams. IdeaStorm allows you to create individual sketches and collections of sketches. To create a sketch just tap the “new drawing” button and start drawing. You can choose from three line thicknesses and five colors to use in your drawings. All drawings are automatically saved in the app.
IdeaStorm does not require or even offer the option for creating an account. Students of all ages can start using the app in a matter of seconds. One drawback to IdeaStorm is that drawings can only be shared if you take a screenshot of them, save them to your camera roll, and then share from your camera roll. Overall though, it’s an easy app to use and could be good for students to use to quickly record ideas during a brainstorming session.
