Don't Rely On Screen Size For Calibration; Use A Vernier Calliper The accuracy of this app utterly depends on entering the correct value of your screen size during calibration. However, the phone's reported specs may not be precise. Eg, my Galaxy J7 has a 5.5" screen, but the tape was correctly calibrated only with a value of 5.45". The app thoughtfully provides a small ruler for "verification" in the calibration screen, which you should check with a vernier calliper and adjust the screen size value accordingly to obtain correct readings.
Not easy to use! I keep hitting the power button while taking a measurement. Galaxy tab a 8 inch.
Good enough, if you know your screen size. All I needed was an approximate size for my crochet and turns out it needs calibration confirmation. I ended up finding and using an old sew & knit gauge, which I then used on my crochet project instead. XD
Very useful app Great for small or big items. It's easy to use when you read the instructions carefully
Complete garbage doesn't even work the way the directions intend it to
I had to move the app myself. Waste of phone space.
