### 1/5 — Does not work.

*2016-01-29, version 1.1.3*

Your app does not work. When I press on the calculator the screen freezes. I would like my money back.

### 5/5 — Stair Calc Pro

*2014-10-30, version 1.1.2*

Outstanding Application! I bought this application having never built a stairway in my life.(zero carpentry/framing experience). It took a few minutes to figure out how to enter the values that I knew (overall height etc.) and it figured out the rest! I drew the stringer template based on the values it gave me and the stairs turned out PERFECT!!
