Smart Ruler is the first app that I developed. It is in the 1st set of Smart Tools suite. When I tried to develop a distance-app, I saw a similar iPhone app. At the time, there was no such app in Google Play, so that I had developed it for 2 days. I have updated it for 5 years. :-)
※ How to use??
1) Put an object on the screen of your device.
2) Adjust its left edge to the left of the screen.
3) Touch the screen, and adjust its right edge with a red line. That's it.
