The calculations are clear, the tools are straightforward, and it’s easy to find the information you need without wasting time searching around.If you’re trying to determine how much ventilation you need, what type of ventilation will work best, or which products are right for a particular job, this is one of the best resources I’ve found.

This is the best way to calculate vents needed per job. As a contractor this app is a lifesaver!
Problem with pitch tool
La5t1
This was a great app until it no longer would take photos with the pitch tool on iPhone. It will take a photo but none of the pitch info is super imposed on the photo.
