Onki

Memorize anything

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Sharpen Your Mind, Day by Day. Forever for free. Learn anything with Onki. Onki is an Anki-inspired memorization app built around a modified FSRS algorithm (Free Spaced Repetition Scheduler). FSRS adapts to your memory strength so you spend the least amount of time studying while retaining more. Here's how it works: once a day, Onki shows you only the cards you're due to review. After each card, you rate how well you remembered it, and FSRS reschedules it for the right day in the future. Pick "Forget" and the card resets — its memorization process starts over from the beginning. Free, now and forever. No ads, no gimmicks. Every in-app purchase is just a tip or a donation.

• Card Suspension: You can now suspend cards! Freezing a card removes it from your active study rotation and statistics without losing your progress. • Deck-Level Languages: Set default front and back languages for an entire deck right inside the new Deck Settings. • Support Onki: Tips have moved over to Ko-fi! You can support the app at ko-fi.com/oladipupo. • Bug Fixes: Fixed minor bugs and made performance improvements. Thank you for using the app. I hope it helps. Remember to walk outside with friends and family. :)
