Perfect Push Up

This app lets you make sure you are doing a push-up properly by using the proximity sensor on the front of your android device to calculate how close you're face is to the phone. This can also be used as a push up counter.

**PLEASE READ**
How to use:
First, place the phone on the ground where you will be doing the push up.
Be sure that the little sensor next to the front facing camera is going to be able to detect your face. You can do this by moving your hand over the front of the phone until it beeps(make sure the volume is turned up).

Do your push up and when you go down far enough the device will beep, which means you can go back up.
As you are doing this, the device will keep track of how many push ups you have done. And you can reset the tracker at any time to start over.

You can elevate the phone if you think you are going down to far by placing your device on a book or two.
