Ratings and reviews

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.

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".

Does what it says without annoying ads. Screen size calibration didn't work precisely with a Poco F3. I recommend calibration with a credit card.
