Not accurate
This app does not work. It gives you different numbers every time.
Update looks great
I love this app since it includes so much free functionality include duct sizing, pt chart, and store locator. Great work.
Not working
Not working on iPhone 4S since iPhone update. Deleted it
No Metric Ductsizing
The duct section is useless for engineers who do work globally.
