Tired of long study sessions? We use artificial intelligence to accurately predict when you need to review. Welcome to efficient and effective memorization.

We retain information best when it's a struggle to recall each time we quiz ourselves. If it's too easy to recall, that doesn't mean it will be easy to recall in the future. If it's too hard to recall, then you forgot and that's not good at all. But if it's just the right amount of struggle, then you can remember an extraordinary amount with very little studying! The difference is profound.

The problem is, how do we space out recall attempts so that it's just the right amount of struggle as often as possible? This is where shines.

We use artificial intelligence (AI) to help determine the spacing between recall attempts. Our algorithm is continuously updating based on how you perform and the content of the cards you work with; it learns as you learn. This is unlike any other memorization platform. Over time, will get to know you so well that it can predict the perfect memorization timing far better than you could yourself!

What if you need to cram information quickly? is also for you. Review decks quickly and easily with our Cram mode, designed for studying in a compressed amount of time.

Best Memorization App Ever

The optimization of spaced repetition permits efficient and effective memorization that quizlet or Anki can’t provide.

Literally Quizlet with more features; there’s no reason not to use it.

Best App For Studying!!

I use this every time I have an exam coming up. It makes studying so simple and efficient. Whenever I use the app, I am always able to ace my tests and quizzes.

Not only that, but it allows me to keep refreshing my memory on old topics so that I don’t forget them. This feature came in really handy when was time for my final exams since it essentially had my study during the whole year! It reduced so much stress for me during the final exams.

One thing that’s very important for me in an app is the UI/UX, and has beautiful graphics and an easy to use interface.

I can’t recommend this app more!! Especially if you are a student, this app is a must-have.

Might need another debugging for iOS 12.3 app crashes every 30 seconds

Developer Response ,

Hey, sorry to hear about that. I’ve since made an update to the app fixing a number of bugs and adding lots of features, can you try it again and tell me if it still crashes? Thanks, sorry about the crashing.
