Nope
There is no reason for a scale to require my location data to function.
Response from developer
Hello, we are sorry for the inconvenience caused. Our iOS version of the app does not require location permissions; only the Android version requires location authorization due to system limitations for Bluetooth connectivity. Could you please let us know if you encountered any other issues? We would be happy to hear your feedback and assist in resolving any concerns. Looking forward to your further contact!
