Questions
Is Cardpile a subscription?
No. Cardpile is a one-time purchase. Start free, then unlock once to lift every cap — yours forever, with Family Sharing. Every other craft FSRS app rents; this one is bought.
Can I bring my Anki decks across?
Yes. Import an Anki .apkg export and your cards, the deck name and the layout
come with you in seconds — no rebuilding from scratch.
What is FSRS, and why does it matter?
FSRS-6 is the modern spaced-repetition algorithm: instead of fixed intervals, it learns how well you know each card and schedules it for the day you're about to forget it, so you study less and remember more.
Where are my decks kept?
On your iPhone, and — if you turn on sync — in your own iCloud, which only you can reach. There's no account to make and nothing of yours lives on a server of ours.
