Drill

Flashcards that come back right before you forget.

Drill is a spaced-repetition flashcard app for iPhone. Bring your Anki decks over as .apkg, or type a few words, and Drill asks you each card just before you would forget it — every schedule kept, entirely offline.

Drill has no server. There is no account, no analytics and no ads. Your cards live on your iPhone and, if you turn it on, in your own private iCloud. Importing, exporting and studying are free; Drill Pro is a one-time purchase.

What it does

Imports .apkg files with images and your existing schedule; importing the same file again updates text and never duplicates a card.
Cards from text, CSV, Quizlet exports or Kindle clippings; question–answer, reversed and fill-the-blank cards; photos and short audio clips.
SM-2 scheduling (FSRS optional with Pro), a study day that starts at 04:00, undo, flags, a daily reminder, streak and forecast.
Export everything — or one deck to share with a classmate — as a zip that Drill reads back.
