★★★★★ App appears to be a free app but once you enter it you are presented with only purchase option or a short “free trial” that they want to charge you for again.
★★★★★ I'm not going to SUBSCRIBE to a protractor.
★★★★★ Horrible app, asks for a subscription
3 of the 1 and 2 star reviews.
★★★★★ First thing it asks for is to sign up for subscription.
★★★★★ After that you must pay for an account.
★★★★★ This requires you to sign up for a free trial to use it, after which you will automatically be charged $2 a week to continue using it.

★★★★★ You can't use the app without paying $3/week. Complete waste of time.
★★★★★ The problem was I was doing a color by angles page that my mom printed and this app got the answers super wrong

★★★★★ I found this in the App Store. I was surveying a property and I had one angle to start with. Building a schedule of angles was easy. But mastering the protractor tool and angle tool took some time to replicate those…

App appears to be a free app but once you enter it you are presented with only purchase option or a short “free trial” that they want to charge you for again. This app should be removed from the App Store & I want all my information removed from their possession.
I’m not going to SUBSCRIBE to a protractor. Get lost. Onlinerulers.com worked for me instead
The app is very well designed but I just can’t get why the need to charge a weekly subscription for a tool that’s not going to be used that often, why not just a one time fee?
Bad
Protractor on auto reads half the actual angle.
This app is the greatest invention in human history. I use it all the time and it is very practical. Definitely download.
