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.
