Dr Network is an app that monitors the signal strength of your mobile network and notifies you when you experience signal loss. It provides you with detailed information about your phone, including the network operator, the sim operator, the device's serial number, the device's IMEI number, the phone type, the country code, the roaming information, the device's manufacturer, model, device name, its serial number, the device's release version, the SDK version, the Android version, and its root information.

It also provides you with information about your phone's battery, including its level, health, power source, technology used, temperature, and voltage.

The app is free to use, but you will be required to provide a valid email address and a mobile number to receive alerts and information about your network.
