NOT ACCURATE for iPhone 6 Plus
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.
