How to choose a spaced repetition app
Recense 팀 작성 · 2026-06-25 업데이트
"Best" depends on what you are learning and whether you will stick with it. The app you open every day beats the powerful one you abandon. Here are the criteria that actually predict whether you will keep going, and where the popular options land.
What should you look for in a spaced repetition app?
- A modern scheduler (FSRS): it decides when you review, and it is the single biggest factor in efficiency.
- Import: can you bring decks you already have (Anki .apkg)? Re-typing thousands of cards kills momentum.
- An interface you will open daily, because the best algorithm is useless if the app is a chore.
- Offline study and sync, so a commute or a flight is not a lost session.
- Sensible defaults: you should be reviewing in minutes, not configuring.
- A fair price, ideally a genuinely useful free tier.
How do the popular options compare?
| Recense | Anki | Quizlet | |
|---|---|---|---|
| FSRS scheduling | Built in | Yes (recent) | No |
| Import .apkg | Yes | Native | No |
| Modern interface | Yes | Dated | Yes |
| Offline | Yes | Yes | Limited |
| Free core | Yes | Yes (iOS paid) | Free tier with ads |
How do you weigh the criteria for your case?
The list above is not a scorecard where the most ticks wins; the weights depend on you. If you study on the bus, offline and a phone-first interface matter more than raw configurability. If you are coming from years of Anki, import is the deciding line, because a tool you cannot move your decks into starts you at zero. If you are brand new, sensible defaults beat power, because every setting you have to learn is a reason to quit before the habit forms. Decide which two criteria are non-negotiable for your situation, and let the rest break ties.
Which app is the honest pick for which person?
If you want maximum control and live in add-ons, Anki is unmatched, and a power user who has invested in its ecosystem has little reason to leave. If you want quick study games for a test this week and do not need the material after, Quizlet is fine and fast. If you want Anki's proven scheduling without its interface (FSRS, Anki import, a clean app you will actually open, free to start) that is exactly what we built Recense to be. For a closer head-to-head on that last case, see our Anki vs Recense comparison.
Bottom line: the best spaced repetition app is the one you will open daily, so weigh FSRS scheduling, deck import, and an interface you enjoy against how you actually study. Anki wins on configurability, Quizlet on quick quizzing, and Recense aims to give you proven scheduling in an app worth returning to, free to try.
자주 묻는 질문
- What is the best spaced repetition app?
- The best one is the one you will use daily. Prioritise FSRS scheduling, deck import, and an interface you enjoy. Recense combines all three with a free core; Anki wins on raw configurability; Quizlet suits quick, short-term quizzing.
- What makes a spaced repetition app effective?
- A modern scheduler like FSRS does the heavy lifting, because it times each review to your forgetting curve. After that, deck import and a daily-friendly interface decide whether you actually keep the habit long enough to benefit.
- Do I need a paid spaced repetition app?
- No. Recense's core (FSRS study, decks, the community Hub, and Anki import) is free, and Anki is free on desktop and Android. Pay only if a specific feature earns it.
- Is Recense good for languages specifically?
- Yes. It is language-agnostic, handles any front and back pair, and the Hub is built for sharing vocabulary decks.
