Didn’t expect much from the app, but I found it surprisingly easy to use. Actually, it’s too easy to use. Gives me additional way to control my heater Doace heated vest without pressing on the vest buttons manually. This is extremely useful when I wear the vest as an added layer under a winter jacket. I don’t have to unzip the main jacket to access the vest’s buttons. Only thing I’m not sure is how it connects to the vest. It’s definitely not Bluetooth. Very clever.

Simple, uncomplicated interface. Would like to see a BATTERY STATUS BAR.

Does not work for heated socks. App only shows a coat. Users guide has QR code for app but when installed on my iPhone, only clothing that the app functions with is a coat. Not the socks as pictured in the guide. Have to operated functions manually which can be bothersome when dealing with multiple layers of clothing to access the operating button.
