Read full descriptionHide full description
Audio Cards is a completely free flashcard app built for learners who want to study without interacting with thier screen. Hear the front and back of each card with high-quality text-to-speech, then rate your recall with Anki-style spaced repetition. Enable hands-free mode and review by voice: flip, repeat, again, hard, good, easy, pause, and end. Hands-free review — Voice commands during study sessions (microphone used only when hands-free is on). Spaced repetition — SM-2 scheduling with Again, Hard, Good, and Easy. Fully offline — Decks and review history stay on your device. No account required. Import your decks — CSV paste/file import and Anki .apkg import (text/images; cloze not supported). Stats — Daily reviews, streaks, due forecast, and deck-level charts. Touch controls are always available. Permissions for microphone and speech recognition are requested when you turn on hands-free mode.
