Internet Commander PRO is "just" the KEY to unlock all Pro Options of Internet Commander FREE!!!
That means that Internet Commander FREE needs to stay installed after the activation.
After the activation (clicking on the "activate" button in Internet Commander Pro) the app "Internet Commander Pro" will no longer be visible the App Drawer, to not disturb, but is still installed on the phone. And needs to stay installed -> do not delete it


Additional options:
- Night Mode
- Task Killer
- Fully configurable interval for time triggered options
- White List apps
- Peak Mode
- Traffic check before stopping internet
- and many more

As Mobile Internet and WiFi are of the most battery draining options in Android OS they need to be managed properly.
Regrettably Android has (had in Android >=5.0) no solution for this "problem" and here is where Internet Commander comes into play.

Internet Commander is an fully configurable app which will automatically handle your internet connection by turning it on when it is needed and off when not.
