How many times have you thought "you know, this battery widget would be much better if it had some sort of spinning thing around it." or "I would really like to see my remaining battery percentage in the center of a flower."? If you've ever muttered either of the above (or anything similar), the solution to your quandary just landed in the Play Store. It's called Animated Battery Widgets, and if you can't figure out what it is just by reading the name, then I feel sad for you.
There really isn't much to say about Animated Battery Widgets past that. It costs $0.99 in the Play Store, and should satisfy your craving for some sort of animated gadgetry on your homescreen. Oh, and keep up with how much battery you have left, too.
