About this app

Ranked #1 Education app in multiple countries world-wide. Featured in the New York Times.

Learning Chinese characters? Kanji? Medicine? Another subject with lots to memorize? With that much to learn, you need the right flashcard app, to get the most from your study time.

That's why AlgoApp uses an improved form of Spaced Repetition (SRS), built with Artificial Intelligence (AI), to maximize the amount of learning you get done in each study session. When you go to study, the AI chooses which flashcards you need to work on, based on a detailed analysis of your progress. It's like a coach, for your brain.

Make your own flashcards, styled how you like. AlgoApp lets you use colors, bulleted lists, and more. Or search through millions of flashcards that are ready for you to download. Your choice.

You get all this power, wrapped in a simple, polished app.

SIMPLE

• Format your cards using colored text, bulleted lists, underlines, and more, all without knowing CSS
• Flip your decks to study back-to-front, with a couple taps
• Syncs automatically with desktop, web app, and your other phones and tablets
• Create decks on the go
• Make cards using photos from your camera

POWERFUL

• Automatic translation
• Automatic furigana generation annotation for Japanese kanji

USER-FRIENDLY

• Study at any time; doesn't force you to study cards on a rigid schedule

• "Night Mode" that's easy on your eyeballs when studying in the dark

Simple way to memorise things if you can find the right set of flashcards. I like it. Edit: Ankiapp is named after a popular cross-platform app called Anki. The official Anki app is called Ankidroid and it is open source. Ankidroid is less simple but has much higher quality card decks and much more control over when you see cards again. I have switched to Ankidroid. Also, Ankiapp kept asking me for feedback long after I left my review.

Unusable. Autocreated one deck, but no way to use it. it's just locked on the screen and nothing happens. May just be very bad UI design as there appears to be some sort of menu along the top but it's entirely hidden by the Android s status bar.
