[APP][4.0+] Shake (acceleration) meter - simple shaking game, how fast can you shake?

[mil84]

Hi, I developed - just for fun - very simple app (or game?), all you have to do is shake with your phone as fast as possible, and compare yourself to other people in the world (Top 10 score). It's just super simple app which you can use when you are boring or waiting for a train or so,so please take it in this way

Link to game is here:

However, if you have any tips or suggestions, feel free to write me - if reasonable, I will implement them
Thanks
