Ratings and reviews

A great protractor app! I'm easily annoyed by ads, and they're the most common reason I rate apps lower, but they're unintrusive enough here to not take off a star. I've confirmed the plumbob is accurate to within 0.1 degrees, though this is likely dependent on your phone hardware.

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.

As a woodworker, I might use this and it seems OK, but could do with markings for commonly used angles like 45, 15, 30, 60 or these numbers highlighted. Also when using the touch setting there should be an option that will snap it to those angles because it's just too fiddly to hone in to the exact angle. If it had those features then it could be genuinely useful, otherwise it's just a novelty.
