SeeLevel - visual clinometer

I got this to be able to measure tree height for a new hobby of finding champion trees. The cost of a good clinometer is a bit much for a hobbyist. I bought a tripod adapter for my iPhone, which is a necessity for accurate results. You can not accurate results trying to hand hold. To verify the accuracy, I measured the ground to soffit height of the roof of my house which was exactly 26’9” using a Leica Distometer laser. This app measured it at 26.7’ which is basically equivalent( less than 1”

I use the inclinometer frequently for hiking trail building and design. Easier to use and sufficiently accurate for everything but actual transit required accuracy. The level functionality is outstanding!

App is fast, interface is simple. Aim and read the angle, just what you want for skiing.
