Ruler® App Reviews

The ruler is a very nice app. The FAIL is calibration. Or lack thereof. On this 6s, the 80mm mark is an Actual 93mm. So huge fail. All it has to do is measure correctly and it does not. Uninstalled immediately. Third ruler app I have tried. All three measure 93mm at the 80mm mark on this 6s.

This ruler is NOT accurate for iPhone 6 Plus. Theyve simply enlarged their rulers from the smaller iPhone screen, which gives inaccurate measurements on the larger Plus screen. This makes it worse than worthless - it makes it dangerous, because it gives you the wrong info. I ruined some expensive paper because I cut it in the wrong place due to this apps measurement. Not cool.

A ruler should do one thing well, measure. This app is a great concept but it is not accurate. I checked my setting to make sure I was not zoomed. I am set to standard on my 6 plus.

Cant get millimeters. And I hit the upgrade button and it closes the app. I dont think thats what that button is supposed to do

This app doesnt work and it is apparently just used to sell other apps. Dont waste your time.

Not enough measurement options for me though.
