User Reviews for 3-in-1 Ruler

Doesn't work as advertised

Apparently, the only way this app will work as an onscreen ruler is if you give it access to your camera. Why would I need to do that to use it as a simple onscreen ruler? FAIL!

I didn’t do what I needed it to do

Like whatever I was trying to measure something… I was trying to measure a dog and I didn’t take. so. I will not recommend this app

I tried this app and it works well

I don’t understand why crazy people leave bad reviews for a free app. This app seems to work exactly as advertised. Thank you for making this available.

Beautiful and easy to use

Simple, clean, just as advertised, and exactly what I was looking for. Would love to see it gain comparability for the iPad Air 2.

Three ways to measure when you don't have a measuring tape or a ruler: 1 – AGAINST YOUR SCREEN Simple and precise for small measurements. 2 – IN AUGMENTED REALITY Place a virtual measuring tape on a vertical or horizontal surface, such as a wall, table or floor. Built with ARKit. 3 – USING AIRPRINT Print a ruler! Accuracy depends on the printer, so check the result against the on-screen ruler.
