# Smart Vibration Meter・Detector vs Sensor Logger

The clearest difference is rating: Sensor Logger at 4.8 against Smart Vibration Meter・Detector's 4.1. Sensor Logger also leads on ads (none vs shown) and update cadence (weekly vs every 8 months). Smart Vibration Meter・Detector's advantage is review sentiment (60% vs 44%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Smart Vibration Meter・Detector sells 17 in-app purchases, starting at $0.99 per 7 days and Sensor Logger sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Sensor Logger holds the better App Store score, 4.8 against 4.1. Both are backed by a comparable volume of ratings — 27 and 112 respectively. Written reviews complicate that: 60% of Smart Vibration Meter・Detector's written reviews are positive against 44% of Sensor Logger's, so the app with the better star average is not the one people write more warmly about.
