Service Keeper is an Android app developed by IMA Tec, which falls under the Utilities & Tools category. It is a free app that helps to reduce the bug that makes widgets stop updating on Android. If your device is updatable to Android or above, it is recommended to update it instead of using this app. Devices other than Android do not need this app.

To use Service Keeper, install it and launch the app once. After that, if the Amedas widget is not running, it will automatically restart. The app has been updated several times, including the latest version 1.10 released on January 3, 2016, which supports traffic jam information widgets. The initial version 1.00 was uploaded on June 11, 2014, with support for the Amedas widget.
