Ratings and reviews

terrible app. nothing like depicted in the ad for it. can't adjust between duct materials. it doesn't even tell you what kind of duct material it's basing things on. completely useless.

Simple to use, I checked it against a reliable paper version and they were both the same. 👍👍

duct sizing is correct but airflow and fri tion calculations are off by hundreds. refer to smacnas calculator. not that.hard guys. fix it
