Blue Head Buddy is a little app that fills a gap in the Android operating system.
If you use a Bluetooth headset in your car you propably know the annoyance of turning on bluetooth when you start driving and shut it off when you are at your destination.
An alternative would be to let Bluetooth on all the time but this wastes battery life.

Here comes Blue Head Buddy into play.
Whenever you receive a phone call, Blue Head Buddy activates Bluetooth and turns it off when the phone call is over. You can configure Blue Head Buddy to let Bluetooth turned on when your configured headset has been connected while Blue Head Buddy turned on Bluetooth. After the headset disconnects, Bluetooth is turned off again. This can be helpful if you want to call someone back because your phone lost connection.

Blue Head Buddy can also be used as a Bluetooth control widget.
