The clearest difference is rating: EMF Radiation Detector Reader at 4.5 against BLE RSSI Meter's 3.5. EMF Radiation Detector Reader also leads on ratings volume (4.7K vs 11).

Written reviews complicate that: 58% of BLE RSSI Meter's written reviews are positive against 53% of EMF Radiation Detector Reader's, so the app with the better star average is not the one people write more warmly about.
