Start today, nothing to build.
Not sure what to make? Browse a library of ready-made decks and start learning in one tap — languages, world geography, science, and more.
Flashcards that show up on every unlock.
Or on a timer, or when you open your timewaster app of choice. Real spaced repetition, on Android, on-device, yours forever.

New here? Here's the whole idea.
Etch is a flashcard app for remembering things — Spanish vocab, world capitals, a painting and its artist, a symphony from its opening bars. It shows you each card right before you'd forget it — that's spaced repetition, the method that makes things stick.
Start with a ready-made deck, make your own, or import from another app. The twist: instead of waiting for you to open a study app, the cards come to you — or sit down for a full session whenever you want to go deeper.
Made for curious learners — from language students to exam-takers to Anki users who want a cleaner, more intuitive workflow.
A card before you scroll.
Opening Instagram for the fifth time today? Answer a card first. Twenty minutes deep in TikTok? A few more, on a timer you set. You decide which apps, and how often.
Quiz yourself on any image.
Cover parts of a diagram, map, or screenshot, then tap to reveal what's underneath — anatomy, a wiring diagram, the countries on a map.
See each card right before you'd forget it.
Reviewing right before you'd forget is one of the best-established findings in memory science. Etch uses FSRS, a modern spaced-repetition algorithm, to time each card for your target retention.
Coming from Anki? Bring your decks.
Etch reads your .apkg files and carries your FSRS
scheduling and progress across — every card lands right where you
left it in Anki. You stay in control of the details: map every field to
the front, the answer, or extra context, and image-occlusion
notetypes come across as real occlusion cards.
Audio, images, and formatting come across too — every card is
re-rendered in Etch's own clean, consistent style. The rare thing it
can't fully translate, like LaTeX math (not rendered yet) or a missing
media file, is flagged with a count at import, never dropped silently.
And your data isn't trapped: export back out any time to CSV or
.etch.
Local-first. Actually.
No account. No cloud sync. No analytics, no Firebase, no ads. The only data that leaves your device is what you send yourself — an export, an import, or a feedback message you confirmed.
Anonymous crash reporting is off by default — one toggle in Settings → Privacy turns it on. Read the full privacy policy →
