MintDeck
A free iOS flashcard app built around the FSRS spaced-repetition algorithm, with Anki and CSV import, hands-free audio study, and offline use included at no cost. AI-generated decks and quizzes are the only paid part, sold as a one-time credit pack rather than a subscription.
Pros
- Core app with unlimited decks, FSRS scheduling, and offline use is free with no subscription
- Imports existing Anki decks and CSV files directly
- AI credits are a one-time purchase, not a recurring charge
Cons
- iOS only, with no Android or web version
- AI deck and quiz generation requires paying for credits; it is not part of the free tier
- No company or country information disclosed on the site
