# Peak vs BrainFox

The clearest difference is rating: Peak at 4.7 against BrainFox's 4.0. Peak also leads on ratings volume (146K vs 40) and review sentiment (63% vs 53%). BrainFox's advantage is iOS requirement (13.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Peak sells 10 in-app purchases, starting at $2.99 per month and BrainFox sells 4 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Peak holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Peak has 146K ratings behind it against 40, so its average is the more settled of the two. Written reviews point the same way: 63% of Peak's written reviews are positive against 53% of BrainFox's.

Peak ships an update fortnightly, BrainFox every 9 days. The most recent releases landed on September 25, 2026 and September 6, 2026 respectively.
