# Vibration analysis vs Motor Noise Analyzer

The clearest difference is rating: Motor Noise Analyzer at 5.0 against Vibration analysis's 4.0. Motor Noise Analyzer also leads on monetization model (free vs free with in-app purchases) and update cadence (every 3 weeks vs every 3 months). Vibration analysis's advantage is ratings volume (43 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Vibration analysis sells 2 one-off in-app purchases and Motor Noise Analyzer sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Motor Noise Analyzer 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.

Vibration analysis ships an update every 3 months, Motor Noise Analyzer every 3 weeks. The most recent releases landed on September 21, 2026 and August 27, 2026 respectively.
