WiSave is an Android application developed by Stefan Ćertić, which allows users to configure their WiFi settings to maximize battery life. The app is designed for those who are always on the go and need to conserve their phone's battery life as much as possible.

With WiSave, users can turn off their WiFi at specific times of the day, such as during the night or when they are at work. They can also choose to turn on their WiFi each hour or few hours when the display is off. This feature is particularly useful for those who want to stay connected to their WiFi network without sacrificing battery life.

In addition to these features, WiSave has many more options to help users optimize their WiFi settings. The app is free to download and use, making it an excellent choice for anyone who is looking to extend their phone's battery life without sacrificing connectivity.
