# Vibration analysis vs Accelerometer ∞

The clearest difference is ads: Vibration analysis at none against Accelerometer ∞'s shown. Vibration analysis also leads on iOS requirement (15.6 vs 17.0). Accelerometer ∞'s advantage is update cadence (every 2 weeks vs every 3 months) and rating (4.3 vs 4.0). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. Vibration analysis sells 2 one-off in-app purchases and Accelerometer ∞ sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Accelerometer ∞ holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 43 and 61 respectively. Written reviews complicate that: 57% of Vibration analysis's written reviews are positive against 50% of Accelerometer ∞'s, so the app with the better star average is not the one people write more warmly about.

Vibration analysis ships an update every 3 months, Accelerometer ∞ every 2 weeks. The most recent releases landed on September 21, 2026 and September 17, 2026 respectively.
