Always On: Clock for Android 4+

Always On application will always display clock in your Android device just like in Samsung and LG devices. If you are using Android 4 & up then you also can have this feature on your phone by using Always On application. It's very similar to Nokia glance screen.

As per dev this app works best with AMOLED displays since only a portion of the display works which means that it doesn't drain your battery. But you can use in your phone too the only difference is If your device doesn't have Amoled display then battery utilization will be bit more.

It is recommended to keep the "brightness" and "clock -> opacity" in the app's settings as low as possible to conserve battery usage.



Features:
-Changing the font of the clock from 700 different fonts! (PRO only)
-changing the font size
-changing the font color
-changing the opacity of the clock
-choosing whether to show seconds or not
-choosing whether to use 24-hour mode or not

The app is available free but with in app purchase to get pro version, where more customization options are available.

Note: Always On does not work with third party screen lockers. So ensure to delete or disable any third party locker if you have one.
