# Vibration analysis vs Sensors NM

The clearest difference is rating: Sensors NM at 5.0 against Vibration analysis's 4.0. Sensors NM also leads on update cadence (every 4 weeks vs every 3 months). Vibration analysis's advantage is ratings volume (43 vs 4). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Vibration analysis sells 2 one-off in-app purchases and Sensors NM sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sensors NM 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 4, 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 63% of Sensors NM's.

Vibration analysis ships an update every 3 months, Sensors NM every 4 weeks. The most recent releases landed on October 26, 2026 and October 21, 2026 respectively.
