Car Handsfree Helper

Frees driver's attention and saves battery power by managing the bluetooth adapter of the smartphone. Works in the background.
The application monitors the activity of the user and switches bluetooth on automatically on his phone so that it is able to connect to the car hands free system. After exiting the car the application automatically switches bluetooth off.
The user is free to turn off bluetooth at any time, for example when the application switches it on while using the subway or other transport where you are not the driver.
The single screen has 4 buttons: start, stop, turn bluetooth off, and restart.
The application works in the background, starts when installed and doesn't need user input. If you wish you can open the main window and use the buttons to stop the application, start it, restart it and turn off bluetooth.
When the application turns bluetooth on or off it shows a message in the notification bar. Clicking the notification opens the application window.
The paid version is ad free.
