This is one of the first apps on the store to measure height of a ball, any building, your balcony or depth of a sinkhole or just about anything else that comes to your mind.
This app can give you a reasonably close measure of the height of any point or the depth of a drain.
It is also a wonderful play app to see who among friends can throw a ball the highest and throw a ball the fastest.
This app relies on simple and reliable physics formulae to give an accurate answer. This is not a random answer generator!!
