Buggy

From my point of view the world does not need a gesture based calculator. I tried it and I can say the classic "+" button is faster and simpler than gesture. If you need multiplication and division you have to:
1. swipe
2. press the icon/button

Most important thing, the calculator doesnt work! An example: 100 / 0,5= 0
Guys, you should improve your testing before launching a product. A bad user experience over a broken product.
