# Devim GPS vs Accel Timer

The clearest difference is iOS requirement: Accel Timer at 14.0 against Devim GPS's 17.2. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Devim GPS 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.
