Studio Clock Live Wallpaper is a free Android app developed by PhD Software. It is a simple live wallpaper app that allows you to customize your clock display according to your preferences. 

You can use the app to show the current date and time and change the date format to match your region's customs. You can also choose from various fonts within the app or use your own downloaded font. Additionally, the app provides different color sets that change every six hours, and you can customize your own set. You can also select a background image from your gallery (must be less than 2 Mb) or use a transparent texture.

Other features include an optional banner that shows your battery level and device temperature, a daily counter for device usage, and an RSS feed for news updates. Moreover, the app includes a simple timer that can be activated by pressing the center of the clock.
