Comments on Millimeter - screen ruler app for Android

★★★★★ X · May 9, 2024

Works as good as I need it to! Checked with a caliper, the initial generic calibration was actually within about 0.2% of being correct (was set initially upon app startup at 4.07"). A clear ruler that can fit flat on your screen would work well for your calibration. Remember, calibrate at the largest size measurement device you can accurately align with on the screen. While app can calibrate with a coin, calibration will have less error at I.E., 5.00" vs 0.75".

★★★★★ jessica siu · Feb 25, 2023

I used a 8 mm earring for measurement and it's really accurate. Even with default calibration it shows what it has to show. With the size of a credit card for calibration it comes as a handy tool too if the default falls short, so it's a well done indeed. So now I can at least have an idea when I online shop how big an object is.

★★★★★ RK Ohashi · Apr 24, 2021

When you need to measure something and not carrying a tape measure, what does everyone always carry? Their phone! Shows in either millimeter /centimeter or inches. Highly recommend!

★☆☆☆☆ Eddy Neuret · Jan 13, 2026

Sorry but not being able to do one or two measurements w/o buying a subscription is ... Just encouraging to develop my own app

★★☆☆☆ Karthikeyan K · Jan 6, 2022

Not having any instruction on how to measure. Can we take photo to measure? Or it is possible to upload? What can we do just with ruler?

★☆☆☆☆ Debbie Judy · Jun 20, 2022

I installed this app along with other apps, and I'll be damned if I can figure any of them out. No real instructions.

★★☆☆☆ Dennis Keppner · Nov 29, 2025

$30 a year? Yea, tell you what, I'll trade you a bridge. If I wanted only a display I could have taken a picture of a ruler.

★☆☆☆☆ City First · Jun 5, 2026

Its installation is free. Everything is paid
