SIGMON is a free Android application developed by Ditjen PPI Kominfo, the Indonesian Ministry of Communication and Informatics. This utility and tools app allows users to measure the current internet speed and radio performance of their mobile phone's network service.

With SIGMON, users can conduct various tests to assess their network performance. The app features an internet speed test, web browsing test, video test, and route test. These tests provide users with valuable insights into the quality and stability of their network connection.

One of the notable aspects of SIGMON is its commitment to improving network infrastructure. Any bad spots or issues identified by users through the app will be followed up by Kominfo for network improvement. This proactive approach ensures that users can contribute to enhancing the overall network experience.
