I was buying molding at Lowe's and left my tape measure in my truck. This app worked great as a replacement.
Sure, it's just a ruler. But it does exactly what it needs to. I'm not bothered by ads, I'm not repeatedly offered a premium subscription, and I don't get endless notifications asking me to go out and measure stuff. Much respect to the developer.
Video ads = uninstall. Your ads at the bottom of the screen were unobtrusive. Having to wade through video ads just to get to a convenience app that I only occasionally use? That's no going to happen.
I like this app! Very recommended. Barely any ads! The only two things they could work on is to have a more easy to use calibration system and to be able to type in the size of the measurement you want. But really good
Too many adverts!!!!! Amount seems to go up everytime you use it. Cannot even open the app without one popping up and then having to wait for it to close before you can use the app. Dont bother to install
Very nice I like it when urgently need to take measure.
Not good for measuring d size real ruler would be better
Always useful for measuring small items should the need arise. Rather a real ruler but thats not the apps fault, just a phone thing.
Great. Got me out of a scrape a few times when I needed an accurate measurement. Accurate and can be calibrated.
Ads are acceptable when they are unobtrusive, the newer ad system made me wait 30 seconds to measure something... I'll find a paid one instead.
It's okay. Whenever I need to measure something small I keep returning to this app. Big plus: ads are barely noticeable.
Great app to have on your phone, so you can easily measure things. It's simple to use when you need a ruler. 👍
Its great. Very user friendly. Gives me an ideas of the size small objects will look like.
It's okay, need something better. Doesn't have cm and mm broken down on ruler to show actual measurements.
Very useful app in your pocket. Anytime, anywhere you need it..👍
This app does exactly what I want, a portable ruler and very precise on my samsung a8...good job to developer 😎
Excellent tool! Provides a very useful tool for measuring.
More useful on a tablet than a phone, but a great app nonetheless.
Full screen video ads with sound. That's all you need to know.
Can not measure the short side of screen. AIDA64 can get sizes of screen in millimeters, why calibration not automatical?
The app works fast and the measurements are precise.
Terrible now since ads dominate. Fortunatley there are better aps out there.
Not removable overlay with adds is killing the app.
Really useful set of tools to have handy.
This app auto updates itself even though auto updates are disabled and so is auto updates for this app
perfecting virtual measure as needed.
Just downloaded it works real well. This app. Exactly what I need
Yea that's my name... just wanted to share my story with this app. Great easy install and accurately measured the distance between my wheel nuts when I was looking for a new spare. Exactally ,100mm . Second hand Rims are so hard to find new is pricey. Excellent tool. Although not sure how I calibrated without a ruler. But it was accurate out of the box.
