Think of Eidetic as the modern flashcard for the iPhone and iPad. Eidetic uses a memorization technique called spaced repetition, which helps you commit information to long term memory. Whether you’re cramming for a test or need occasional reminders, Eidetic notifies you when it’s time to study. Outside of coursework, Eidetic is helpful for memorizing pin codes, phone numbers, addresses, and passwords. If you have an iPhone and iPad, Eidetic will store what you’re memorizing to iCloud so you can study on either device. You can download the app for free from the App Store, unlocking tests via inexpensive in-app purchases.
