📝 About this app

BRAINYOO is the flashcard app you can use to quickly and easily quiz yourself on large amounts of educational content. It helps you memorize vocabulary and study for classes like medicine, law, history biology and many more.


BRAINYOO is perfect as an app for your classes in school, to help you prepare for your finals or to prep you for exams in your college classes.

Do you want the opportunity to learn more effectively, faster and better? You can create your own flash cards to go along with your school or college classes. Our index card app quizzes you using special algorithms perfectly adjusted to your own memorization speed, saving you a lot of time in the process.

Shortly before a test, you study with your flash cards using BRAINYOO’s specially developed power mode to help you pass the test with confidence. The index card app shows you your individual progress, so you always know how far you are from your goal.
After the test, you switch to Leitner’s long-term memory mode, which saves the latest knowledge in your memory for your high school or college final exams.

BRAINYOO is one of the best learning apps for schools, because teachers can also use the flashcard app to create and share their own flash cards with their students in study groups. Teachers can also access their students’ learning statistics and even administer tests such as vocabulary tests in the learning app.

With BRAINYOO, you can work on virtually any subject – all languages, including English, French, Spanish and Italian, as well as math and science:

Use the flashcard app to prepare for your tests in all school and college subjects – all languages, including English, French, Spanish and Italian, plus math and science too:

– Incorporate pictures, eBooks, videos, audio, LaTeX formulas and links into your flashcards and format the flashcards however you choose.

The premium version of the learning app enables you to use our app a lot more effectively:
– Create study groups, share your own content with them and track the learning statistics of your school or college students or employees
– Simulate tests and evaluate the results right there in the flashcard software
– When learning languages, you can take a picture of a book page with the flashcard app and automatically create index cards with any words you don’t know
– Use the dictionary function to learn the vocabulary
– At school, you can easily convert the vocabulary pages of your textbook into flash cards by taking pictures of them, and then use them to study
– More memory and unlimited creation of flashcards
– Export your index cards as XML
– Tell your learning coach which index cards you need to have in your brain for the test and by which date, indicate when you will have time to study and your learning coach will completely organize your studying for you.

Or you can get the inexpensively priced Premium-Light upgrade, so you can study without seeing advertising.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
