# BLE Scanner 4.0 vs Magnetometer+ Metal Detector

The clearest difference is rating: BLE Scanner 4.0 at 4.3 against Magnetometer+ Metal Detector's 3.0. BLE Scanner 4.0 also leads on ads (none vs shown) and ratings volume (615 vs 8).

Written reviews complicate that: 58% of BLE Scanner 4.0's written reviews are positive against 100% of Magnetometer+ Metal Detector's, so the app with the better star average is not the one people write more warmly about.
