Cliff Height Timer

This is a very simple app that uses basic physics to tell you the height of a cliff or the depth of a well. All you do is time how long it takes for the object to hit the ground and let science do the rest. You can even measure the height of a cliff from the ground if you throw a rock right up to the top and start timing at the apex.
This app was inspired by Science/Design/Creativity YouTuber Mark Rober.Photo by Powderruns (https://flic.kr/p/35XkCo)

I really like the app, but it would be nice to see a bigger play button and a tap anywhere to start feature just because sometimes I miss the button because I am watching the falling object. Very good app though.

So the YouTuber that made this app I'm very happy that someone would spend this much time making an app just so we don't have to do math thank you

Would be better of the readings were to a few decimal places, other than that it is a fantastic estimation tool

Does exactly what it says, would like the explanation page like the iOS version but still good.
