Invasive, Intrusive, infuriating. I have more than 1 x Bluetooth device - believe it or not, as do billions of other people. When I want to use other devices, I should be able to without being bombarded with this app trying to connect. when I force stop the app, I don't want it to appear 1 second later draining phones resources. When I want a different watch face, it should not need to delete the previous face. How pathetic - 1 watch face at a time? Asks for a huge amount of permissions.

Used to work great, now unable to personalise watch face, once photo is selected and transfer icon pressed, keep getting "push failed" notification. Further to afore mentioned, now will not connect to the phone, therefore cannot synchronise or pair to allow functionality. Not much use now? unless there is another compatible app?

The app is great but it stopped working properly after an update. I have to reinitiate Bluetooth all the time in order to connect the watch for syncing. Max/Avg/Min not showing the values for the heart beat, also the text colors are not clear to read due to the background color, I suggest white. It will be nice to have blood pressure monitoring like the one for the heart beat.
