Ratings and reviews

Works as good as I need it to! Checked with a caliper, the initial generic calibration was actually within about 0.2% of being correct (was set initially upon app startup at 4.07"). A clear ruler that can fit flat on your screen would work well for your calibration. Remember, calibrate at the largest size measurement device you can accurately align with on the screen. While app can calibrate with a coin, calibration will have less error at I.E., 5.00" vs 0.75".

I used an 8mm earring for measurement and it's really accurate. Even with default calibration it shows what it has to show. With the size of a credit card for calibration it comes as a handy tool too if the default falls short, so it's a well done indeed. So now I can at least have an idea when I online shop how big an object is.

UPDATED REVIEW: When I 1st installed this app, I tried calibrating w/a CC. I couldn't get it 2 work, since I was unable 2 use my keyboard. Maybe it was operator error, OR maybe there ought 2 B better instructions 4 calibrating this way. After getting my screen size 4 my Galaxy S9, (FYI it's 146.5mm, 14.65cm or 5.8 in, 4 those who need it) I chose the 3rd option 4 calibrating w/my screen size. WOO-HOO! It worked! So apparently it was operator error. I revoke my 1 star & give u 5 star's! Thanks!
