I downloaded this all and all I really needed was the angle measurement in degrees. That worked. For a time. After a new update the developer decided to charge for an upgrade that would allow you to measure for degrees. It defaulted to radians. To add insult to injury the degrees only works part of the time. Basically this app is a fail now. I want my .99 back. I no longer trust this developer. Will not purchase anything from him again.

Genuinely disappointing. I have never seen an app go through so many measures to force you to buy the upgraded version, even apps that don’t offer a free version do less to convince you to pay them. It’s defaulted in radians and if you try to use degrees it will prompt you to buy premium. Just about every feature is a premium feature, meaning unless you’re forking over the money for premium it’s just a radian protractor. Even just trying to use the radian protractor will periodically prompt you every set amount of seconds spent moving the measuring slider about not owning premium and lock you out of touching anything in the app for 12 seconds. It’s not even an ad, it’s just telling you to buy premium. I think I’d be less annoyed by incessant ads, banners, etc than by someone’s intently programmed measures to inconvenience anyone using the free version without any intent of at least gaining money by showing ad slots or anything of the sort.

If you want to pay money this may be a good tool, but I could not even test it due to all the ads for their other apps. Want to see degrees instead of radians? Great, pay to upgrade or wait 13 seconds until this option disappears then make sure you don’t press it again. Not sure what this vague button does? Go ahead and press it, probably an ad. Wait you’ve already been using the app for 30 seconds, even though over half that was ads? Well your time is expired and now you need to wait 15 seconds before you can use the app again, unless of course you upgrade!I might’ve paid for it if the demo worked ok, but I deleted it in under a minute because the free version is useless without any features and the way the developers push you to buy features constantly makes me doubt if the features actually work.

All I wanted was to be able to measure angles on my phone. When I first opened the app it showed a bunch of neat products, but I really just wanted to be able to measure a few angles real quick. It finally let me skip past the upgrade option and took me where I wanted to be. Then when I finally got to the measuring device, everything was in radians and it would not let me switch to degrees without paying. So am I to believe I have to pay a dollar to unlock every single option in this app? Seems ridiculous. And while I was messing with it while the app was measuring in radians, nothing ever moved anyways. So I couldn’t tell that it was working at all. I spent a total of about 1 minute on here, so I could have missed something. But overall was disappointed enough to spend five minutes writing this review.
