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.

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!

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!

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.
