Balance - pocket scale 5.0
It works yeah!
Take a look by your self
1) Place your iPhone up on a classical bottle of wine
2) Center your iphone right in the middle of the bottle. The orange cursor must indicates zero. (Hit your iPhone (by using a pen) until the orange cursor will indicate 0. This means your iPhone is perfectly balanced and ready to work)
3) Place the object on the far left of the iPhone on the orange circle
