About this app

Smart Ruler is in the 1st set of the Smart Tools collection.

This app measures the length of a small object by touching the screen.

Usage is very simple.
1. Put an object on the screen of your device.
2. Adjust the object to the left of the screen.
3. Touch the screen, adjust the red line and read the length.

* Main features :
- Multi-touch
- Meter <-> Inch
- Background color
- Material design

I calibrated the app on a lot of Android devices. If it is not accurate, you can enter the actual width with [Calibration] menu.


* Pro version added features:
- No ads
- Caliper mode
- Architectural and Engineering scales
- Ruler extension
- Protractor, level, thread pitch

* Do you want more tools?
download [Smart Ruler Pro] and [Smart Tools] package.

I was buying molding at Lowe's and left my tape measure in my truck. This app worked great as a replacement.

Sure, it's just a ruler. But it does exactly what it needs to. I'm not bothered by ads, I'm not repeatedly offered a premium subscription, and I don't get endless notifications asking me to go out and measure stuff. Much respect to the developer.

Video ads = uninstall. Your ads at the bottom of the screen were unobtrusive. Having to wade through video ads just to get to a convenience app that I only occasionally use? That's no going to happen.
