This reminds me of a bluetooth toothbrush I just bought that requires my location to be enabled to change the settings via the oral b app which is required since this model has less buttons than others.
The reason why I bought a bluetooth toothbrush was for a wireless hardware clock, brushing timer, and ranking system which also really doesn't work correctly even with the app.
