### 2/5 — Need to add “forgot my password”

*2020-11-13*

This app comes in handy occasionally for figuring out chimney height on a pitched roof or something. Seems to work ok. Now my issue is that I had to get a new phone and I don’t remember my user name or password and there is NO WAY TO RESET IT. There is no “forgot my password” link or anything I can see. So now it’s useless to me. There isn’t even an option to create a new account.. very frustrating.

### 2/5 — Inaccurate

*2019-03-04*

Calculation such as the pitched roof chimney height are in accurate. The app offers no reference to any of the material from any of their books and is simply a collection of five formulas. I would’ve liked to have seen something with more reference material.

### 4/5 — Great tool for the pros

*2017-10-11*

This is pretty great but the extension calculations for cathedral ceilings won’t work on my older iPhone, I am unable to scroll up to include run and get the calculation done
