# Accelerometer vs Vibration analysis

The clearest difference is ratings volume: Vibration analysis at 43 against Accelerometer's 1. Vibration analysis also leads on iOS requirement (15.6 vs 17.6). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Accelerometer sells 1 one-off in-app purchase and Vibration analysis 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 4.0 for Vibration analysis. That said, the two scores are not equally well evidenced: Vibration analysis has 43 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 57% of Vibration analysis's.

Accelerometer ships an update every 5 months, Vibration analysis every 3 months. The most recent releases landed on June 9, 2026 and September 21, 2026 respectively.
