The classic apps make you wait days between reviews and bury you in a due-card backlog. fastcards flips it: every session leans into the cards you keep missing, with a light refresh on the ones you know — adaptive practice tuned to your weak spots. No scheduling, no backlog.
Every session ranks your cards by how well you actually know them and shows the shaky ones far more often — up to ~5× — while the solid ones drop to a refresher.
There’s no due-date queue to fall behind on. Study whenever — every card is still in play, just weighted toward what you need most.
Upload lecture notes, a textbook chapter, or a photo of a page — AI drafts the cards, grounded in your document, and you review before saving. Or import an Anki .apkg with audio intact.
