"Handy no fuss app."
Aleks Grabowski
"You can use the calibration with a ruler to get this pretty exact. In my case .756 was the magic number."

Nucleus Rhyme
"Samsung S9... initial ruler was relatively precise... about 1mm difference on 10cm. Calibration made it terribly wrong. 1.1cm difference on 11cm. Since it's nothing else but a ruler I deinstalled it again."
