Angle Pro

The app loads horizontally, which I prefer, but it only loads in one orientation. You can't rotate it to the most convenient side. I prefer the volume slider on top and this app loads with the volume slider on the bottom.

So I'm ordering a knife sharpening system, which benefits from being able to check ACTUAL angles vs the angle markings provided on the sharpening system. So I downloaded this free app: It's very accurate and stable, even showing .1 degree changes. It has a very clean interface. It uses either the side of the phone or the back of the phone to calculate angles from (selectable by an on-screen icon). It isn't flooded with adds. It's very responsive. I can't find a single complaint at all. It's not a trigonometry/calculating app, but I don't desire/need that. I was immediately impressed, compared it to other free apps, then deleted those other free apps: for the above reasons TOGETHER, this, to me, is the superior app of those I compared. Thank you developer! A surprisingly great, non-annoying free app.

Excellent level and angle application. Even reads accurate with a protective rubberized case on iPhone. Often compare it with a 7 foot spirit level by placing it on top or on the side for vertical applications and so far they always read exactly the same. Use it a lot and I am very pleased.

I downloaded to use as a Goniometer to measure moments of patient's joints/flexibility.... So far works perfectly for what I need compared to other expensive apps.... Thanks for making free!

Nice little tool for measuring the angle of a small run. Large level is better for distances. Use a water level (aquarium tubing plus colored water) for very large distances.
