# N+Motion vs Vibration analysis

The clearest difference is rating: N+Motion at 5.0 against Vibration analysis's 4.0. N+Motion also leads on in-app purchases (none vs 2) and update cadence (every 6 weeks vs every 3 months). Vibration analysis's advantage is ratings volume (43 vs 1). 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. N+Motion asks for nothing beyond the download.

N+Motion 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.

N+Motion ships an update every 6 weeks, Vibration analysis every 3 months. The most recent releases landed on September 17, 2026 and October 14, 2026 respectively.
