Comments for Android

★★★★★ This is a really handy app to find the angle/slope if something. Also, handy for leveling a trailer. Thanks

★★★★★ I quickly needed a protractor to determine the tilt of a small platform I'm designing. The app was exactly what I needed and it worked perfectly!

★★★★★ Simple app. Allows you to find angles from plumb and has an interactive protractor.

★★★★★ Simple and accurate, have been using it for several years.

★★★★★ Tried a few other apps, but this one is real easy to use the rest are overcomplicated nonsense when all you need is an easy to understand and use app and this is perfect for the job.

★★☆☆☆ Uninstalled after first attempt to use the camera function, needs to many permissions and hundreds of cookies enabled to work, I gave up after turning off access to 120 tracking cookies and wasn't even a third of the way there.

★★☆☆☆ I swear this app moves the image without your input when using the camera mode. Very frustrating

★★☆☆☆ Absolute garbage. Whenever I wanted to use the app an add took over and I couldn't even x it out. I couldn't even use the back button to get out of it I had to actually close and reactivate the app, and it started all over again Don't even waste your time.
