Hot Spot Starter is a mobile application designed to activate the Wi-Fi hotspot of your Android device automatically as soon as it connects to a Bluetooth device. Developed by Thomas Junge, this app is specifically designed for users who are tired of manually turning on the Wi-Fi tethering feature on their smartphones when their in-dash car handsfree unit connects via Bluetooth.

The app features several setup options, such as shutting down Bluetooth at disconnect, selecting specific Bluetooth devices only, and ignoring Bluetooth LE connections. In addition, users can choose to start selected apps with the hotspot, making it easy to access specific apps like radar warners every time they connect to the handsfree unit. The WiFi state is always restored automatically after Bluetooth disconnect.

One of the most significant aspects of this app is that it will only start the hotspot if the device is charged. Hot Spot Starter is available in a free version that users can test before purchasing the full version. It is essential to note that the app is not compatible with Android 11 and above, and no app update is possible due to the unavailability of technical solutions.

Overall, Hot Spot Starter is an excellent solution for users who need an automatic Wi-Fi hotspot activation feature for their Android devices. It is easy to use and has several setup options that allow users to customize the app to their preferences.
