Ruler-caltor APK 2.01g

Ruler-caltor is a handy tool that turns your smartphone into a ruler. The ruler is calibrated automatically on the first run and after reset but you can also calibrate it manually yourself with a real ruler.

The Option page provides several settings to let you set up the ruler according to your preference. If anything goes wrong, you can always use the Reset function to reset the app.

Using measurement lines allows you to record down measurements. The recorded measurements can then be used in the calculator page to do some simple calculations.
