Eidetic uses a technique called spaced repetition to help you memorise anything from important phone numbers to interesting words or facts.

It works differently from typical brain training apps by using items that have meaning and context.

Perfect for students looking to remember those key facts or anyone who wants to remember friends phone numbers, new bank details or just cool words, quotes or facts you come across!

Eidetic uses notifications to remind you when it's time to test yourself. By spacing the tests out over time it helps you to retain the information in long-term memory, this is known as the 'spacing effect'.

Built in flashcard types make it easy to add items:
‌ • Dictionary
‌ • Phone Number
‌ • Fact
‌ • Number
‌ • Quote
‌ • Note

Simple intensity levels allow you to select the length of the testing period. For those who need to remember the information quickly you can cram it into one day or if you want to learn it more naturally you can space it over 2 weeks or a month!

Intensity Levels:
‌ • Cram - 1 Day
‌ • Normal - 2 Weeks
‌ • Casual - 1 Month

Simple and effective

I'm only using this for phone numbers, so can't comment on more involved projects, but works well for this! Knowing my son's and other family phone numbers was a great little project, recommended app.


Haven't used yet but seems useful...

Only one problem. App seems to be able to access contacts despite it not having permissions (in privacy).



Don't ever let the ratings put you off! An app that will keep you on your feet when it comes to remembering everyday encounters- like word definitions, quotes and facts. All you do is type in your entry and choose how often you want to be tested.. And there you go!! Whether it's a months repetitive test or one day.. You will never forget a THING!!
