Peek vs Anki vs Quizlet
A fair comparison of the three most common flashcard apps for language learners.
| Feature | 
Peek
| Anki | Quizlet |
|---|---|---|---|
| Spaced repetition (SRS) | ✓ | ✓ | Limited |
| No sign-up required | ✓ | ✓ | ✗ |
| Free cloud sync | ✓ | ✓ | ✓ |
| Multiple study modes | ✓ | ✓ | ✓ |
| Mobile-first design | ✓ | ✗ | ✓ |
| Free on Android | ✓ | ✓ | Freemium |
| Language learning focus | ✓ | General | General |
Honest note: Anki gives power users deeper control — custom scheduling intervals, dense settings, scripting. Peek trades that depth for a clean mobile app built around language learning.

Ask Peek
Tap a question, Peek answers.
Is Peek free?
Yes. The Android app is free to download and use, including cloud sync across devices.
How is Peek different from Anki?
Peek is mobile-first and built for language learners. Anki gives power users more control over scheduling and settings, but its iOS app costs $25 and most configuration lives on desktop. Peek is free on both Android and (soon) iOS.
Which languages can I learn with Peek?
Spanish, French, Japanese, German, Korean and Dutch. Every card comes with native-sounding audio pronunciation, so you learn how words actually sound, not just how they are spelled.
What language is the app in?
English. Menus, buttons and the translations on the cards are in English, so you learn, say, Spanish through English.
Do I need to sign up?
No. You can start using Peek right away without an account. Create one later if you want to sync your decks and progress across devices.
When is iOS coming?
The iOS version is in development. We have not set a fixed release date yet.
How does spaced repetition work in Peek?
Each card has a review schedule. If you remember it easily, the next review is pushed further out. If you stumble, the card comes back sooner. Over time, you spend less time on cards you know and more on cards you forget.
Where is my data stored?
On servers located inside the European Economic Area (EEA). Your data never leaves the EEA. You can delete your account and all data from inside the app at any time.
