I'm fussy when it comes to my device wallpaper. I like them dark and I don't like them getting in the way of what I do with my Android devices, that being, be productive!
I've experimented with live wallpapers in the past, mostly the ones that come with the device, but usually I've ended up replacing them with a plain background.
As an application, there isn't much to say here. It's a configurable clock that sits on your device as live wallpaper. You can change the color, if you display the second hand, day of the week and month. You can resize the clock with three options (small, normal and large) and you can realign it on your screen, so in my case I have it biased towards the top of the screen.
It doesn't do much but what it does, it does very well and that's not interfere with the normal use of my device with glossy over-the-top effects.
Do you have a favorite live wallpaper that helped make your device productive? If so, share with us in the comments below.
