SeeLevel - visual clinometer

I got SeeLevel a week ago. The inclinometer, for which I bought the app, does not work. The inclination always reads NAN, even after an apparently successful calibration. For you non-computer folks, NAN means not-a-number and indicates that the inclinometer, at least, is seriously broken. I emailed the app’s author through the link in the Apple App Store explaining the problem but it’s been a week with no reply. The app has not been updated in 4 years. I have an iPhone 12 running IOS 15.3 so maybe I shouldn’t be surprised the app doesn’t work. My bad for not suspecting this before I bought the app. If you run similar hardware or IOS version buying this app is like throwing your money in the street. If I get an app update that fixes the problem I’ll revisit this review.

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

Not intuitive and user guide doesn’t help.

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” difference) I used an iPhone 6s with a tripod about 30’ away from the house on sloping ground. It is simple to use, but not intuitive, so read the guide.

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!

This app replaces a $200 clinometer fairly well. I have had a couple glitches, but all in all I am very satisfied

This app is just what I was looking for. In addition to measuring the angle of the phone, you can use it to measure the height of a vertical object if you know the distance to the base, or you can measure the distance to an object of a know height. The app does all of the trig automatically. You view the object through the camera, and it displays the level horizon on the screen along with the angle or height above or below level. So you can measure the height of an object where the bottom is below your eye level and the top above, just add the two numbers. If there is one problem, it is that the gyro chip in my 5s seems to not be as accurate with the phone held vertically as it is laying flat. You can calibrate it in the app, but I can't seem to get mine better than about 1.5 degrees. So if you view a distant object that you know to be at eye level, it may show level horizon to be above it. This doesn't seem to ruin the height or distance measurements because the angle error is the same at the top and bottom of the object. But if you need angle from a true horizon, it might not be accurate enough. Maybe the chip in the 6 and 7 are better.

Handy clinometer to have on a phone

Does me no good if it won't open. Yes I have calibrated it

So I'm attempting to put in tracking solar arrays on a sloped hill. I need to know the angularitys of the sun from East to West and on the south. I view the east west and southern tree lines to know how many trees I need to take out. This app is awesome.
