TC66C

Requires location acces to function and can't control the trigger functions. Has 3 useless buttons at the bottom for navigating the display on the actual device, which you probably can't see if you have to use the app. The only good feature is the graph, which the device itself is lacking.

Mediocre app, works fine. For anyone wondering about why it needs location access... Google placed bluetooth under location permissions. This needs location access to talk to the bluetooth device.

This app is garbage, asks for device read/write and location permissions, won't work without.
