GP02Monitor is an Android application developed by Yusuke Kikuchi that allows you to monitor the antenna level and internet connection status of your EMOBILE WiFi router, including GP02, GP01, GL02P, and GL04P. It also displays the battery level, data usage, and bit rate. The app features a detailed display window and a simplified status bar display.

The app automatically starts monitoring when it is launched and can be set to monitor specific SSIDs. The status bar icon displays the battery level or antenna level (in the form of an icon) and the internet connection status (3G/LTE) in a single icon. The app also hides the status bar icon when the internet is disconnected or when disconnected from GP02.

Please note that new features will no longer be added to the app, and only bug fixes will be made from Version 3.00 onwards. The app is licensed under GPLv3, and the source code is available on GitHub.

If you encounter any bugs, you can report them through the Google Play comments section or via email. The developer may also provide updates on Twitter (@ac100v_net), but please be aware that the developer may not be able to fulfill all requests due to personal interests.
