Ruler Try this app yourself and make your own mind up. If not suitable then delete app. Doesn't interfere with anything else so nothing to lose. This app gave a rough indicator but would certainly recommend anyone to get the right tool for the job if accuracy is important.
There are few problems app UI is nice but it lags and does not support full screen. Idk about pro version but please fix those bugs I will support you. accuracy is perfect though out of the box. Like the fact it's ad free Kudos for that
Don't have any idea why... But I have tried everything to change it from centimeters to inches... Can't do it and that should be something that is unavoidable. Something that even if you were an idiot you would stumble into and even do by accident.
Useful App but still can be better Adding up a two boxes to get exact length and breadth if you need to see how it will look like would add more value. Adjusting through touch screen and arriving at exact dimensions is little difficult and time consuming.
Needs finer calibration Clean and relatively easy to use, but not accurate. On my Nvidia Shield tablet, off by about one part in 150. The calibration is too coarse: 1.00 is too long and 0.99 is too short. Needs to be calibrated in thousandths.
Great app but only for metric measurements No ads or access permissions asked. Easy to calibrate. Nice features. Seems to have a slight calibration inaccuracy. After calibrating, the ruler was still slightly shorter than calibration. Had to go back to calibration and make longer than measured.
