A free app for Android, by ForestTools.

This app can be used to estimate the height of the tree. It is useful for forestry students and for anyone who needs to become familiar with measuring heights. It is not a professional height meter, but it is easy to use and the results are good.

The app uses one of two methods to measure tree height: E+2Winkel (distance plus 2 angles) or 3Winkel (3 angles).

The first method is a bit easier, but the results are not so accurate. The second method is more accurate, but it is a bit more difficult to use.

The first method requires you to measure the distance to the tree. This can be done by counting step length or by using a tape measure.
