Evernote has released an update to its Evernote Peek study app for the iPad 2 adding support for audio clues, shared notebooks and additional UI improvements and bug fixes. Evernote Peek is an app designed as a study aid for iPad 2 and Evernote users, allowing the iPad 2 Smart Cover to be used to “peek” at clues and hints by lifting the edge of the Cover; users see a clue and can then open the Smart Cover all the way to see the answer. Closing the Smart Cover automatically advances the app to the next clue, allowing users to quickly quiz themselves on a notebook of study materials. Evernote Peek 1.5 introduces audio clues in addition to the visual ones and includes three new audio-based notebooks to try out: birds calls, Spanish language and French language. The latest update also adds support for accessing notebooks shared by other Evernote users. Evernote Peek is available from the App Store as a free download.
