# HelioPeak vs Accel Timer

The clearest difference is update cadence: HelioPeak at every 3 days against Accel Timer's every 4 weeks. Accel Timer's advantage is iOS requirement (14.0 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. HelioPeak sells 1 one-off in-app purchase and Accel Timer sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

HelioPeak ships an update every 3 days, Accel Timer every 4 weeks. The most recent releases landed on October 7, 2026 and October 14, 2026 respectively.
