Google Creative has released a new experimental Android app called Meter which is worth trying on every smartphone. With Meter you can set a special and "live" (animated) type wallpaper on the main screen of your Android phone which shows colored geometric figures whose filling indicates some system status information.
Conceptually, the background is a dynamic image that functions as a widget and displays information regarding the battery level, the Wifi signal and notifications .
For example, as you can from the figure above, a triangle may appear as the background of the screen showing the Wifi signal strength or a circle showing the battery charge level and which becomes smaller when it runs out.
The backgrounds alternate randomly every time the screen is turned on, so once you will see the triangle, once the circle and once the square which is divided into bars and which indicates the number of notifications received.
The backgrounds are live not only because they change dynamically depending on the moment, but also because turning the smartphone they move according to gravity.
Meter's background also appears on the lockscreen when the phone is locked.
The app worked well on my Nexus 5 although from the comments I have read it still has many bugs and may not work on other models.
However, it is worth downloading Meter from Google Play, also because it is completely free.
Although it is a one-of-a-kind application, the idea of a system information wallpaper had already been applied in another app called Device Info Live WallPaper .
The background, in this case, shows many numbers indicating: Date and Time, CPU usage, Battery, RAM usage, Free memory, network, Wifi and technical specifications.
