I have never had a problem cutting stairs before the iPad.
I always divide the rise by 7...........
Say 108/7 = 15.42
So you have either 15 or 16 risers.....depending on distance of run and rise
So 108 / 15 = 7.2
Convert 7.2 to inches.....= 7 1/8 " rise
Anyway, I wonder how a person would plot on a board the points needed to
cut the stairs and with so many measurements.....?
Isn't a square easier?
You also need to cut on a straight line so, you need to intersect your
points of measure with a straight edge anyway.

There is a stair stringer layout tool for the iPad that makes cutting
stringers simple and easy called StairBuilderPro. It is unlike any
other layout tool/guide in that no framing square or angle gauges are
needed. The app plots all of the layout points on the board step by
step and all that is required is to connect the dots and cut. It
takes into account all floor covering thicknesses, tread thickness,
and riser board thickness. Super easy.
