I wouldn’t use it for laying tile but it’s cute when you want to get a rough idea of something. Like if it’s worth moving something big and heavy, you can find out if it’ll fit before you move it, instead of having it be an inch past the corner of the wall or something.

r/IPhoneApps on Reddit: Is there a good ios app that works as a ruler?
May 27, 2025 -

Sometimes I just need to measure small things on the go — like screws, bolts, or packaging — and I don’t always carry a physical ruler. I tried a couple of apps like this phone ruler in mm that claim to turn your screen into a ruler, but some felt clunky or not very accurate.

Has anyone found a reliable phone ruler in mm that actually works well and is easy to calibrate? Ideally something lightweight, no weird permissions, and simple to use.

How accurate is the iPhone’s “measure” feature? - Quora
Answer (1 of 11): Thanks for the A2A. The iPhone’s “Measure” feature is great for ballpark estimates, but it will never be acceptable for anything that requires precision. For instance, if you are measuring a room to see how much paint you will need, it is perfect.
