Admin Alarm is a free Android application developed by DoesTheJob that allows you to monitor the state of servers defined. It is a simple yet effective tool for system administrators or small home server owners to ensure that their servers are functioning properly. The application performs invisible background tasks or operatively shows the information about the servers on-screen. If your server fails, you will be the first to know!

One of the best features of the application is that the background mode does not cause any significant effect on the battery discharge. The traffic consumed is very small, although you should consider your tariff's features when using a mobile network. Additionally, the user manual is available on the developer's website, which provides detailed instructions on how to use the application effectively.
