Millimeter Pro - ruler and protractor on screen

Great little App, and was very accurate on my Sony Xperia XZ Premium just using the standard set up. no further calibration was required ! Being 'old school' (Yes, I still use Fahrenheit too, HATE Centigrade) having inches in both decimal and fractions was a BIG plus for me, OK lots of people may never want or need Inches, but at least the option is there... that says it all about the developers for me, and also I do need to use metric as well. Well done Guys

My Z5 display screen perfectly depicted the measurements as accurately as possible without needing preciseness of calipers. It's standard Calibration method was adequate as far as the naked eye can see!

Nice basic measuring tool, handy when u don't have a ruler on the spot. Works offline and doesn't need to access your phones functions to install. May need pro version if u need it for more the a basic straightedge ruler.

Great and useful tool, just need to measure with real digital caliper the screen of your phone to get the most accuracy. If this app have the option to use camera to measure objects that will be the perfect portable tool. GREAT JOB.

"calibration" doesn't make sense. Couldn't get accuracy under 1mm. Not surprising with its calibration method. Waste of time.

Excellent, but small bug - if you touch screen inside measuring area, you can't then adjust the guides, so you can't hold the item down, eg crinkly postage stamp.

What a great idea working perfectly on my xz no calibration needed as the standard works fine well worth the money

Handy little tool.works really well, even on my cracked screen.

Meaningless app with no features to mark

Neat idea and I was pleasantly surprised. Great for small items. Thank you!

Handy little measure - useful for tension squares in knitting!

Very good nice we have different types of tools in one

Great tool. Thanks.

I dont know how to use this great app..

Very nice app

Great tool

it a nice handy tool for handyman ☺️☺️

Very Useful and Clean UI

It's great. Thanks

Great with pro mode.

Very useful app

Rubbish

Excellent app but a major improvement would be if the screen is touch disabled except for the ruler part and the protractor dial because the slider moves by accident constantly when you put anything metallic on the screen and/or your fingers, making it hard/practically impossible to get the measurement.

Best app for engineers, architects, interior designers, etc

Wow! Amazing...

Awesome app. Only criticisms: it would be good to do calibration by selecting your device from a list, and being able to set an angle would be useful (rather than just divisions of 360)

I am impressed. Very accurate with default calibration. It's a keeper!

Simple and clean. No permissions or Internet use. Nice app to have on standby. Thank you!

Very nice app when you need a quick tool to measure something. Thank you for your effort.

Had error 941 from Google play, but developer very helpful & finally downloaded.

I like it ???? Dose what it supposed to do. Never had any issues. I have used the app for quite some time now.

Using your phone as a ruler is nothing new nor unique. I wish this app could also be used as an on-screen ruler for measuring the length & angle of screen objects, just like the transparent on-screen rulers we have for the desktop screens... [Added] Thanks for the reply! Will do when there's a free version or it goes on discount! Cheers!

works great, I love it, very precise.

awesome & dandy app to have and easy as well.

This is so handy

I think one only ever given a handful of five star reviews since the using the first UK Android device many years ago. This Dev team have implemented feedback suggestions quickly. No dodgy permissions, the app just does its thing without unnecessary feature bloat. Sure Vistech will go on to great things.

I've browsed the ruler apps for a while and this one seemed to be the most useful one. Very functional options, easy to manage. I'm glad to buy you a quarter pint of beer guys :) Add1: The only remark would be that a manual setting area would be useful. Here the user could give the exact digit for the ruler by the keyboard manually. Recently I needed a 6 cm unit and it was a bit tricky to set it properly by scrolling the lines. Thanks.

You can calibrate it neatly with a quarter and then never be caught without a ruler again.
