Mnemo is made by David Oreper. For a question or a problem, email islandowlsupport@gmail.com. Please say which iPhone and iOS version you use and which version of Mnemo (in Mnemo, Settings › About Mnemo).
In Anki on your computer, export a deck as an .apkg file, or your whole collection as a .colpkg file. Save it to iCloud Drive or Google Drive, then open it from the Files app and choose Mnemo, or use Settings › Import deck or backup in Mnemo. To bring your review history and pictures too, keep Include scheduling information and Include media checked when you export. A .colpkg replaces everything already in Mnemo, so Mnemo asks first.
Every feature. Importing is unlimited. Studying is free in one deck, for the first 30 cards you study in it (30 in all, not per day), and those cards keep coming back when they're due. The first deck you study becomes the free deck. Mnemo Unlimited removes the one-deck and 30-card limits, for $3.99 a month or $59.99 once (US prices).
In Mnemo, go to Settings › Unlock every deck (under Mnemo Unlimited) and tap Restore Purchases. Use the same Apple Account you bought with.
In the iPhone's Settings app, go to your name › Subscriptions › Mnemo. Cancel at least 24 hours before the current period ends to avoid the next charge.
Open a deck, press and hold the Study button, and choose Quiz me hands-free (Study ahead hands-free when nothing is due). Mnemo reads the question. Say your answer, or say "show", and Mnemo reads the answer back. Then say "wrong" (Anki's Again), "hard", "good" or "easy" to grade the card. Say "repeat" to hear it again, or "stop" to finish.
No. Mnemo has no account and no sync server. Your cards move by file: export from Anki and import into Mnemo, or the other way round. Mnemo can also back up your collection to a folder you pick, about once a night (iOS decides exactly when).
No. AI help uses Apple Intelligence on iPhones that have it. A key is optional; see the privacy policy for exactly what is sent when you add one. Without either, everything in Mnemo except AI help works the same.
