# Leitner Box Flashcards vs Mopiq

The clearest difference is update cadence: Mopiq at weekly against Leitner Box Flashcards's every 5 weeks. Mopiq also leads on ratings volume (1.4K vs 35). Leitner Box Flashcards's advantage is review sentiment (83% vs 69%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Leitner Box Flashcards sells 2 in-app purchases, starting at $1.99 per month and Mopiq sells 10 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Mopiq holds the better App Store score, 4.7 against 4.6. That said, the two scores are not equally well evidenced: Mopiq has 1.4K ratings behind it against 35, so its average is the more settled of the two. Written reviews complicate that: 83% of Leitner Box Flashcards's written reviews are positive against 69% of Mopiq's, so the app with the better star average is not the one people write more warmly about.

Leitner Box Flashcards ships an update every 5 weeks, Mopiq weekly. The most recent releases landed on October 25, 2026 and October 30, 2026 respectively.
