What Cardpile does
One job, done well: help you remember what you study. Cardpile pairs the modern spaced-repetition algorithm with a clean review loop, brings your existing decks across, and lets AI draft new cards from your notes — all in an iPhone app you buy once, not rent.
FSRS spaced repetition
Cardpile schedules every card with FSRS-6, the modern free spaced-repetition scheduler. Instead of fixed intervals, it tracks how well you actually know each card and brings it back on the day you’re about to forget it — so you spend less time reviewing and remember more. This is the algorithm the Quizlet and AnkiMobile crowd switch apps to find.
The craft review loop
Tap to flip a card, then rate it on a four-button row — Again, Hard, Good, Easy. Under each button you can see the interval that grade would set, so the consequence of your answer is visible before you commit to it. It’s the considered, deliberate review the craft crowd expects, with nothing in the way.
Import your Anki decks
Moving over from Anki? Import an .apkg export and your cards, the deck name
and the layout come straight across in seconds. You don’t rebuild your decks by hand
and you don’t leave years of work behind — the migration bridge is built in,
so swapping a subscription for a one-time app costs you nothing but a tap.
Turn notes into cards with AI
Paste what you’re learning — a paragraph, a list, a page of notes — and Cardpile drafts flashcards from it for you to review. Keep the ones that land, drop the rest; only the cards you actually add count against the day’s quota. A generous free allowance every day, lifted higher once you unlock.
Your decks, on your iPhone and in your iCloud
Make decks, add and edit cards, browse and search — the everyday work stays fast and simple. Everything lives on your iPhone, and when you turn sync on, in your own iCloud (CloudKit) so your decks follow you across your devices. There’s no account of ours, and nothing of yours sits on a server we can read.
A real free tier, then bought once
Start free with a usable deck — enough cards, decks and daily AI generations to feel the whole import → review → recall loop before you decide. One purchase of €9.99 lifts every cap to unlimited and raises the AI quota, forever, with Family Sharing. No subscription, nothing renews.
Bring your decks across and study the modern way
The algorithm you wanted, the decks you already have, and a price you pay once.
