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.

I love the idea of the app. Its structure is very easy to use, all at a glance, perfect for organising your flash cards. The problem is that the app is full of bugs. For example, when I wrote some tags the other day, they were with capital letter. Today, I can't write tags with capital letters anymore. I'd love to see the bugs fixed so I can use the app without any frustrations.

Downloaded the app to study & paid for it. Spent two month at sea with no internet making 300+ cards. App started to become buggy crashing every time I made a new card. When home I tried to sync my work in order to save it so I can delete & reinstall the app. Now the app crashes every time I try to sync & the data is not uploaded. Attempted to contact the Developers for troubleshooting help & haven't heard from them in a month.... I like the functionality but don't want to lose all of my work.

Love that I can create flashcards from a laptop then read them off my phone. Copy and paste function is wonky, so you have to reformat everything. You cannot add tags while creating new flashcards which means you have to save the card then go back into it to add tags - very tedious. So you spend more time creating flashcards instead of studying them. Also when pasting photos from PowerPoint or e-textbook, you are limited to formatting it - removing the option to practice identifying diagrams.
