Comments on Millimeter Pro - screen ruler for Android

★★★★★ Lucas Ralston · Sep 12, 2025
I'm only rating this app as it keeps nagging me. It's a good app, I'm enjoying it. I haven't found a real world use for it yet. But when people say "this is the steepest road on the planet" I can now measure the angle!
★★★★★ Kamlesh Bhankharia · Jun 4, 2020
Excellent app with Amazing functionality. It is daily companion of my technical life as an engineer. It's a handy onscreen ruler, level, protector....so on. And yes, all are very accurate with ease of calibration. Like professional tools. Also useful for normal life too. Best measuring app with user-friendly interface.....🙂🙂🙂 I recommend it to every person, a must-have app in smartphone.
★☆☆☆☆ Jose Manuel Gonzalez · Sep 18, 2024
You cannot use this "Pro" app to measure large objects in your environment. You are limited to items that are small enough to fit have to on top of the phone's screen!
★★☆☆☆ Dan S · Mar 3, 2026
It won't let me rate the regular Millimeter because I paid for Pro. But it is beyond shameful that this company tries to rope people into a subscription for the regular Millimeter app. Subscriptions have gotten out of hand. You have got to be kidding. Pro is available for a one-time purchase, but I don't find it useful. A screen is too small to take useful measurements. It works, just not a must-have. Use a tape measure -- and do not under any circumstances pay for a subscription for one!
★☆☆☆☆ Kaushik Vachhani · Dec 29, 2020
There is no virtual ruler like that I want to take measurement of for an example tiles there is no provision so i don't like that. My money go waste.

Description by vistech.projects Written by the developer, not by AppBrain. Click to read.
Millimeter is the best-rated screen ruler with the option to calibrate any Android device for accurate measurements on the screen 📏. It has real full-screen mode and besides common length and area measurements, you will find many interesting features requested by app users:
- circle radius and diameter measurements,
- protractor for angles, spirit / 🔮 bubble level for tilt,
- splitting a segment or sector into equal parts,
- thread per inch (TPI) https://youtu.be/M1Qrbs2bgCY , etc.

Metric and imperial units are supported.

Thanks to feedback from our users the app usability has been improved with features like screen lock 🔒, manual value input, dark mode, the fine grid on/off option. It is a very user-friendly tool for small object measurements or DIY projects.

Supported languages:
- English 🇺🇸, German 🇩🇪, Russian 🇷🇺, Japanese 🇯🇵 , and French 🇫🇷 languages.

☎ Contact us at support@vistechprojects.com if you need any assistance with the app or have suggestions for further improvements. Thank you!

VisTech.Projects Team.
