Remember more with a private, native flashcard library built for focused study—online or off. Bring the decks you already have. Choose Anki .apkg files with the in-app Files picker, or open .apkg and .colpkg files in BuyDaEarf from Files or another app. BuyDaEarf renders common Anki templates with cloze deletions, typed answers, images, audio, and math formatting. Study when it works for you. FSRS schedules each review around your memory, while downloaded decks stay ready without a network connection. Create and edit decks and cards directly on your iPhone, organize nested decks, and choose the number of new cards you want to learn each day. No BuyDaEarf account is required. Your library is stored on your device. If you are signed in to iCloud, BuyDaEarf can privately sync decks, cards, media, and study progress through your private CloudKit database so your library stays current across your devices. Sync requires a network connection; studying downloaded content does not. WHY BUYDAEARF? • Import Anki .apkg and .colpkg decks • Remember more with FSRS spaced repetition • Study downloaded cards offline • Create, edit, and organize decks and cards • Review cloze, typed-answer, image, audio, and math cards • Optionally sync through your private iCloud database • Choose light, dark, or system appearance BuyDaEarf is an independent app and is not affiliated with Anki or AnkiWeb.

Verdict
The clearest difference is update cadence: BuyDaEarf at daily against Mining Gyan's every 12 months. Mining Gyan's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
