Useless at measuring mats
Useless at measuring and cutting mats. What should the interior dimensions be? Who knows.
Response from developer
The interior dimensions are the size of the picture you wish to frame (minus some overlap). eg. 8 x 10 for a large photo, but the size is up to you. You would then add in your desired matt widths (distance from picture edge to frame edge) and the app calculates the external matt size. The external matt dimensions are displayed at the top of the cut list. It is calculated from the picture and matt dimensions you have entered in the app. You cut this size from a large matt sheet, and then cut in from each edge by the dimension you have entered for the matt widths, eg 2" in from the top edge... I hope that helps you out.
