# WBV vs Vibration analysis

The clearest difference is review sentiment: Vibration analysis at 57% against WBV's 0%. Vibration analysis also leads on ratings volume (43 vs 1) and update cadence (every 3 months vs every 7 months). WBV's advantage is rating (5.0 vs 4.0) and in-app purchases (none vs 2). 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. WBV asks for nothing beyond the download.

WBV 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 complicate that: 0% of WBV's written reviews are positive against 57% of Vibration analysis's, so the app with the better star average is not the one people write more warmly about.

WBV ships an update every 7 months, Vibration analysis every 3 months. The most recent releases landed on September 18, 2026 and September 21, 2026 respectively.
