Really love the idea, I've been planning on working on my calisthenics and this was the best thing I've ran across, however, I do have some problems with it.

- I realized that many people have already complained about the sound so I don't think I really need to go into much detail about having optional alarm sounds

- When I had my cam on the ground so it would be able to see my face and detect my head going up and down I ended up having to do about 30 perfect form push ups to complete my goal of 5 push ups. One idea that popped into my head was maybe show some sort of outline for where the face, shoulders, arms, etc. should be so that it could be more efficient in detecting a push up.

- I found that when I kept my laptop on my desk and bent the cam down it had counted all of my push ups which was much less frustrating than when my cam was on the ground.
