Verdict

The call

The clearest difference is ads: BrainGain at none against Peak's shown. BrainGain also leads on chart position (#174 vs unranked). Peak's advantage is ratings volume (146K vs 22K) and device support (4 vs 2). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Peak sells 10 in-app purchases, starting at $2.99 per month and BrainGain sells 8 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.7 for Peak against 4.7 for BrainGain. That said, the two scores are not equally well evidenced: Peak has 146K ratings behind it against 22K, so its average is the more settled of the two. Written reviews are what separate them: 64% of Peak's written reviews are positive against 62% of BrainGain's.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. Both last shipped on November 11, 2026.
