Why does my iPhone keep getting disconnected from my UA Scale?
Your phone connects to UA Scale via Bluetooth. Make sure your scale is within normal Bluetooth range of your phone.
Also note that the scale connects to Wi-Fi® during the weighing process, and cannot simultaneously connect to your phone. If these conditions are met and your iPhone® will not maintain a connection to your UA Scale, please check the version of iOS on your device. Your iPhone® must have iOS 8.4 or later for compatibility with UA Scale.
