µMagnetometer 4+

Doesn’t Work on iPhone

Works ok on iPad but not on iPhone 7+. Cannot find any help facility but figured the three readings at bottom are x, y and z values and figure below is their RSS. No idea what the pallete symbol does apart from requesting access to the camera. Landscape mode on the iPad sets the dial to below zero even though the reading is around 45 as for portrait mode. The display on the iPhone is completely frozen will all numbers at zero. In its present state it is certainly not worth the money and even if it were free it is pretty useless.

UPDATE 1st December 2021: Got feedback from developer asking if location services are on. They are but the app is not listed in location services, either on the iPad or the iPhone. It works fine on iPad. He did not address any of my other comments.

Developer Response ,

Thanks for comment, is geolocation services enabled?

Does not work at all on iPhone SE 2020 iOS 15.5

As others have reported this App does not measure anything as the magnetic field strength sits firmly on zero.

I even passed it over my magnetic gimbal clamp and some transformers.

Ironically even the “rate on the App Store”, in the Apps own settings screen is broken and does nothing!

Luckily for me this App appeared on my free App for the day App.

Note to Developer: Location Services and all necessary settings in the iOS settings App were fine with full permissions given to your App where available. The App just does not work on iPhones as others have reported.
