FSRS (Free Spaced Repetition Scheduler) is a modern, open-source algorithm that uses machine learning principles to model your memory. Unlike SM-2 (used by Anki), FSRS adapts to your individual forgetting patterns, resulting in fewer reviews and better long-term retention.
Correct. $9.99 once, and you own it forever. All future updates included. No trials that auto-renew. No "premium tiers" to unlock later. We believe learning tools shouldn't be a recurring tax.
Yes. Mina supports CSV import, which covers exports from Anki, Quizlet, and most other flashcard apps. You can also use our Web Portal to upload files from any browser directly into your iCloud-synced library.
Upload any image — anatomy diagrams, maps, circuit boards — and Mina uses on-device Vision AI to auto-detect text labels. You can then quiz yourself with tap-to-reveal, type-to-answer, or drag-to-match modes. You can also manually add, resize, and reposition boxes and labels.
None. Zero. Mina stores everything locally on your device. If you enable iCloud sync, your data is encrypted by Apple's CloudKit infrastructure — we never see it. There are no analytics, no tracking pixels, no third-party SDKs.
Yes. Mina includes a fully optimized iPad experience with sidebar navigation, larger card views, and proper multitasking support. One purchase covers both iPhone and iPad.
Mina is a native iOS app with FSRS, image occlusion, and a one-time price. You can import Anki decks via CSV. It does not run Anki add-ons or the Anki desktop editor.
Free keeps 3 decks, FSRS, CSV import, text-to-speech, and quiz modes. Image occlusion, iCloud sync, unlimited decks, and the web portal need the $9.99 purchase.
Download Mina and see the difference real spaced repetition makes.
