# DuoCards vs Brainy

The clearest difference is review sentiment: Brainy at 100% against DuoCards's 63%. Brainy also leads on rating (5.0 vs 4.7) and update cadence (fortnightly vs monthly). DuoCards's advantage is ratings volume (1.5K vs 3) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. DuoCards sells 9 in-app purchases, starting at $19.99 per month and Brainy sells 10 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Brainy holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: DuoCards has 1.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 63% of DuoCards's written reviews are positive against 100% of Brainy's.

DuoCards ships an update monthly, Brainy fortnightly. Both last shipped on November 13, 2026.
