A free app for Android, by Nguyễn Đắc Phúc.

The Airplane Mode Scheduler app allows you to schedule when your device’s airplane mode should be on or off. This is great if you want to save battery and use the device less. You can set it according to the days of the week. You can also set your Airplane Mode to be on all night and off in the morning. It’s perfect if you don’t need it all night.  The app also gives you the option to turn your Wi-Fi connection on or off when you configure your airplane mode settings.
