Why does an app that has nothing to do with phone calls need access to contacts

R70%
by R####:

Essential app for Architect and Engineers who refers a lot to scaled drawings. Good accurate and usable scale ruler. What would make it perfect is to enable custom scales to be set at intervals of five instead of the current ten.

The custom scale is not accurate. It Gives you wrong info. If you do 1:20. , it says 1.9 ft when you are close to 2. It should be 20 ft. PLs the scale is not accurate

I really needed this app to roughly measure an architectural drawing at 1:50. Scales like 1:20, 1:50 and 1:100 etc would be really handy. I found 1:48 ok though. Wasn't sure how to control screen rotation. Would be nice to fix it. Useful app tho, so thank you

This is one of the apps everyone should have. You never know when you will need a ruler and you don't keep one in your pocket. But you probably have your phone there!

Tested app. It worked fine on mine. One thing though, the protractor turns MINUS degree but I cannot see the marker (it is not in view). So it was not usable. And
