It works very well if you use it correctly. Folk saying it rubbish obviously are not getting it

A good use of this app is estimating the sizes of sections on pie charts. Would be even better for this purpose if (in order of usefulness): 1. The camera focused up close. 2. Angles were shown in percent of circle (besides the current degrees and radians). 3. Option provided to show full circle protractor. 4. Possibility to add additional markers.

It was a great little app on the first run, but on the second run after I pressed the camera icon it went into camera-only mode forever, even without the protractor scale, even after I killed and restarted the app. So 1 star instead of 5, lad.

Junk!!!!!! Useless. Does nothing. Inaccurate when other apps are fine, when use camera you see no protractor and it freezes as well. Horrible programming! Typical liar reviews dev got people to do. Every other apl works fine so its the terrible programming not my device. Using Samsung Galaxy S4.

Lovely concept. I gave it 5 stars from my Redmi note 3. But in One Plus 5t, it gets stuck in camera mode without interface icons. Restarting wont help. Had to uninstall. But I really loved this app and hoping they would fix it.

works fine to me.it let me choose or verify angle,have a reference angle to let you know if your droid is in a corect position.check your droid compatibility or read the info before missleading other people for not try any app from google play i know this developer apps and are fine all of them. be responsable. if your phone is a crap that not meant the app is too

An option to flip the numbers (counter clockwise) would be great. Or show the counter clock wise #s below the normal ones. While its possible to just use the reference angle it\'s just faster and easier to have them there.

Works great as a protractor. Plumb lines are a great addition. I can\'t seem to get out of camera mode either, but a reinstall works to get back to the regular mode which works wonderfully.

Found this useful but then my antivirus app found malware on this application after I had been using it for months, so removed it - wondering if anyone else has experienced something similar, or if there is a reasonable explanation for this app being flagged as malware only now.

For anybody who\'s stuck in camera mode with no visible interface - try revoking the Camera permission for this app in the phone Settings. Then start the app again and you may get the GUI back. It worked here.
