Grossly inaccurate

It’s not even funny how horribly inaccurate that this ruler is on my iPhone XR.

Recalibrate and get the 5th Star!!

I also found that on iPhone 7P the ruler pro app measures 1” as 1,1/8”. Is there a way to recalibrate for correction? Otherwise I like the ruler with adjustable redlined so that you can use it like callipers and set small items right on the screen between redlines for accuracy & precision.

In case you’re wondering...

There are no instructions, so finding out how to switch from inches to centimeters may be difficult. The i with a circle around it is the key. But it’s so close to the ad at the bottom of the screen, it took me a bit to realize it’s not a link to give me more information about the ad. The ruler is nice and simple other than that. It’d definitely be nice to have a simple tutorial opening page to explain the options available. The red lines need an explanation (though they can be self-explanatory). Not everything is obvious to everyone.

I got the app but didnt go on it

I am lazy so bye

Waaaaay off

Downloaded to an iPad mini and the scale is ridiculously off.

Inaccurate measurements for 6 plus

One inch is actually about 1 1/8 inch on the iPhone 6 plus. I could not find a way to calibrate the app.

iPad retina

Just downloaded this and checked the calibration against my ruler. It's spot on. Measures in inches and centimetres and their increments. 5⭐️!

Easy to use

Simple, clean design, and easy to use

Not retina

Text and lines are fuzzy.

It's a ruler

It works. It's a ruler.
