# Vibration analysis vs Acc.elerometer

The clearest difference is review sentiment: Acc.elerometer at 100% against Vibration analysis's 57%. Acc.elerometer also leads on rating (5.0 vs 4.0) and in-app purchases (none vs 2). Vibration analysis's advantage is ratings volume (43 vs 1) and update cadence (every 3 months vs every 11 months). On price, ads and device support there is nothing between them.

Both are free to download. Vibration analysis sells 2 one-off in-app purchases. Acc.elerometer asks for nothing beyond the download.

Acc.elerometer holds the better App Store score, 5.0 against 4.0. 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 point the same way: 57% of Vibration analysis's written reviews are positive against 100% of Acc.elerometer's.

Vibration analysis ships an update every 3 months, Acc.elerometer every 11 months. The most recent releases landed on October 4, 2026 and October 3, 2026 respectively.
