# CogniFit vs Peak

The clearest difference is ads: CogniFit at none against Peak's shown. CogniFit also leads on review sentiment (71% vs 63%). Peak's advantage is ratings volume (146K vs 1.7K) and rating (4.7 vs 4.5). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. CogniFit sells 14 in-app purchases, starting at $4.99 per month and Peak sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Peak holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Peak has 146K ratings behind it against 1.7K, so its average is the more settled of the two. Written reviews complicate that: 71% of CogniFit's written reviews are positive against 63% of Peak's, so the app with the better star average is not the one people write more warmly about.

CogniFit ships an update weekly, Peak fortnightly. The most recent releases landed on September 23, 2026 and September 26, 2026 respectively.
