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. ## Key features - Modified FSRS algorithm - Daily card reviews - Recall-based rescheduling - Adjustable difficulty - Ad-free experience ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | $1 Tip | $1.00 | one-time | | $5 Tip | $5.00 | one-time | | $3 Tip | $3.00 | one-time | | $10 Tip | $10.00 | one-time | | $20 Tip | $20.00 | one-time | | $50 Tip | $50.00 | one-time | | $100 Tip | $100.00 | one-time | ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/onki/id6757570439/reviews.md ### 5/5 — Helpful and easy to learn *2026-05-06* Onki uses a spaced repetition framework to help you commit things to memory which is a really helpful way to engage your brain.

Pack-to-Card Deep Search: You can now search for any card content or deck right from the home Packs screen. Tapping into a match carries your search query all the way through to the card view. Give it a spin and let me know if anything feels off. ### 1.4 — 2026-07-15 • 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. :) ### 1.3 — 2026-06-25 - Hands-free study — Press Play and let Onki run the whole session for you. Each side is read aloud, you choose how long to dwell on each card, and you can pause anytime. You still need to select difficulty, "Forgot" is automatically selected when nothing is clicked in the specified time. This improves accessibility for people with certain disabilities or for users who want to study in an alternative way. - Text-to-speech in the right language — Tap the speaker on any card to hear it read aloud. Set a language per card side (English, French, Spanish, Japanese, and more), and a handy EN/FR/JP/ETC badge shows which one it's using. Languages can be selected in the cards settings. - Schedule your packs — Tap the gear on any pack to pick the days you want to study it, and get a gentle weekly reminder only on those days. Every pack keeps its own schedule. - A tidier home screen — Tough, All, Due, and your new Stats button now sit in a clean 2×2 grid, so everything's one tap away. - Dark mode — Onki now looks great day or night. Choose Light or Dark appearances in Settings. Many of these changes were direct requests from the feedback form, so please ask for whatever you want and I will do everything in my power to get it done :). Love ya, call your mom, happy studying. ### 1.2 — 2026-05-24 - Stats chart now shows 30 days by default and lets you switch to 7-day, 6-month, or 1-year trends. Just tap the chart title to open the picker - Fresh installs now come with two extra starter packs: Geography (US States, Canada Provinces, Mexico States, Philippines Provinces) and Spanish (Numbers, Verbs, Nouns) - Secret milestone celebrations :) Thank you for you're feedback. Some changes are directly related to the feedback individuals left. Happy Learning, free forever. ### 1.1 — 2026-05-06 - Brand new Stats page — your learning progress, all in one spot: - Hard, Medium, and Memorized card counts (tap any of them to see exactly which cards landed there) - Current Streak and Best Streak - Cards Matured in the last 30 days - Retention rate based on how often you nail cards on the first try - Reviewed Today and Added This Month to see your daily and monthly work - Due Tomorrow and Total Cards so you always know what's ahead - 7-Day Trend chart that shows how your Hard, Medium, and Memorized cards have shifted over the past week — drag finger across it to peek at any day - Smarter scheduling — we tuned up the FSRS engine so reviews land at just the right moment, not too early and not too late. - See the future — when you're reviewing, you'll now see exactly when a card will pop back up before you tap Again, Hard, Good, or Easy. No more guessing. Thank you for using the app :), I hope it helps.
