# Accelerometer vs G

The clearest difference is update cadence: G at every 4 days against Accelerometer's every 5 months. G also leads on ratings volume (7 vs 1) and device support (4 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Accelerometer sells 1 one-off in-app purchase and G sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.0 for Accelerometer against 3.9 for G. That said, the two scores are not equally well evidenced: G has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 54% of Accelerometer's written reviews are positive against 50% of G's.

Accelerometer ships an update every 5 months, G every 4 days. The most recent releases landed on June 9, 2026 and July 4, 2026 respectively.
