Google Keep is a note-taking app developed by Google in 2013. Keep is available for mobile devices running Android 4.0.3 and higher and via the Google Drive website.
No matter where a user runs the Keep application, notes are automatically synced between the website and the mobile app, meaning they can be accessed anywhere. Users input things like appointments, to-do lists and shopping lists, and everything is kept in an easy-to-read format which is color coded. Photos can be added, as can voice memos, and lists are easily created by clicking on the check mark at the top of the screen.
