Ruler

Sep 4, 2015

New method to calibrate the ruler: using a credit card, or any card following the ISO/IEC 7810 ID-1 standard (most membership or gift cards for instance).

It is now possible to delete a saved measurement from the history list.

Set the length displayed manually, useful for measuring and transferring a known length. (Note: crash when entering an invalid string now fixed)

Display measurements in millimeters.
