The Data and Music Scheduler app is a simple and useful utility that lets you manage your data usage and music listening experience. This app helps you save battery power and earphone usage by automatically turning off your mobile data, Wi-Fi, or Bluetooth, or all of your devices, when you go to bed.

This app is an extremely useful tool for people who stay up all night to use their smartphones, tablets, or any other mobile device. If you are one of those people, this app can help you save battery power and earphone usage by automatically turning off your mobile data, Wi-Fi, or Bluetooth, or all of your devices, when you go to bed.

There is one thing that you need to keep in mind, though, and that is that the app will not work while your phone or tablet is connected to the Internet.
