Smart Watch Toggler

If you have a smart watch that you have connected to the phone as a hands-free device you will notice that the phone no longer connects to the Bluetooth hands-free of the car since Bluetooth only allows for one hands-free device.

This app will solve this by detecting when the car tries to connect to the phone, and will automatically disconnect from the watch and connect to the car instead. This only affects the hands-free function of the watch, the watch will still stay connected to receive notifications etc. Once the car is stopped and disconnects it will re-connect with the watch again.

I have only tested this with my watch (a Samsung Gear S3) and my car (a Mazda with a TomTom system), but with this combination it works well. In rare cases it fails to switch over to the car hands-free (it happens in less than 5% of the connection attempts), but it always succeeds in switching back to the watch when the car is turned off (at least for me). I also use the Bluetooth of the car to play music from the phone, I don't know if this app works differently if you don't do that.

Please comment if you have tested other combination, and write whether it works or not.
