# Peak vs Impulse

The clearest difference is update cadence: Impulse at every 6 days against Peak's fortnightly. Impulse also leads on chart position (#13 vs unranked) and ratings volume (849K vs 146K). Peak's advantage is device support (4 vs 1) and iOS requirement (15.0 vs 18.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Peak sells 10 in-app purchases, starting at $2.99 per month and Impulse sells 14 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Peak against 4.7 for Impulse. That said, the two scores are not equally well evidenced: Impulse has 849K ratings behind it against 146K, so its average is the more settled of the two. Written reviews are what separate them: 63% of Peak's written reviews are positive against 69% of Impulse's.

Peak ships an update fortnightly, Impulse every 6 days. Both last shipped on September 24, 2026.
