Flashcards that work offline, sync everywhere and adapt to your memory

No, though it uses the same kind of modern scheduling that Anki offers. Anki is enormously configurable and works brilliantly once you've learnt how it all fits together. This app is deliberately simpler, for people who just want to study.

It also lets you work together. Decks can be shared, so a study group or a class can build one deck together instead of emailing new versions around.

Yes. In Anki, export your deck as a package (an .apkg file) and import it here. Files from older and newer versions of Anki both work. Your study history comes too, so the app knows which cards you already know well and you don't start from scratch.

Anki's Basic, Basic (and reversed card) and Cloze cards become our single-sided, double-sided and fill-the-blank cards. Other card types are converted to the closest match, and images and audio come across too. The one exception is Image Occlusion cards, which can't be imported.

Yes. Any deck can be exported for Anki with your progress included, so you can open it there and carry on. You can also export a clean copy without your progress, to give to someone else, or a spreadsheet (.csv) of just the text. Nothing you build here is trapped here.

Yes — that's what it's built for. Your decks, pictures and audio are kept on your phone or computer, so the app works with no internet at all.

Anything you study or change while offline is saved, and catches up with your other devices the next time you're online. A six-hour flight is no problem.

It keeps track of how well you know each card and brings it back just before you'd be likely to forget it. Cards you know well come back less and less often, and cards you struggle with come back sooner, so your time goes where it's needed. Many older apps use a fixed rule instead, such as stretching the gap by a set amount each time you get a card right.

As you study, it learns how your own memory works and adjusts to suit you. You can also choose how much you want to remember, from 80% to 98% of your cards: aim higher and you'll forget less but have more reviews each day; aim lower for a lighter load.

For the curious: the scheduler is FSRS‑7, a widely used open-source memory model.

Enter someone's email address and choose whether they can edit the deck or only study it. They'll need an account too. There's only one copy of the deck, so several people can add and fix cards at once and everyone sees the changes.

Your study progress is never shared. Your due cards, streaks and statistics are yours alone, even on a deck a hundred other people are studying.

Not to study. Open the app and start building decks straight away, with no sign-up at all. Your decks are kept on that device.

You only need an account to use the app on more than one device, or to share decks with other people.
