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

Great App, does exactly what it says without clutter. 3 modes each useful for variety of tasks, drawing and measurement based. Interesting use of your phones camera to impose protractor image over. Haven't really tested this mode much, but was pleased to discover this ability and can see numerous situations where this could be useful practically.

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. Edited

Awesome app! I just wish you could tap on the angle and manually put in the degree and then match the desired angle to that number. Unless I'm missing it and it has that option (which is entirely possible) other than that it's exactly what i need. Thanks for the great app 👍

This is a user friendly app that is perfect for me when setting up knives for sharpening. I am able to set and check the setting with ease. Thanks.
