Auto car bluetooth is a free Android application developed by RoncoA that aims to provide a seamless Bluetooth connection between your phone and car speakerphone. The app automatically turns on Bluetooth when you get in the car and connects it to the speakerphone. It also turns off Bluetooth when you leave the car, saving battery life. This app uses Google's Activity Recognition service to detect when you are in the car.

One of the best features of Auto car bluetooth is its simplicity. You don't need to manually turn on Bluetooth and connect to the speakerphone every time you get in the car. The app does it for you automatically, making your driving experience more enjoyable and safer. In addition, the app is very lightweight and easy to use, making it a great choice for anyone who wants to improve their in-car audio experience.
