Featuring cities such as London, San Francisco, and New York, the live wallpapers much like Google Now mirror what is outside your window by cycling through dawn, day, dusk, and night. This app also offers the capability of customizing the settings according to different time zones.

The images change their state only at the predetermined time intervals.

Both the versions are available on the Google Play Store. It is compatible with Android 2.2 (Froyo) and above versions.
