★★★★★
Very useful for fast estimation and calculation. Very flexible at different units.
★★★★★
Overall I like the app. What I don't like, every time I start the app I have to click on "duct size velocity" ant to set 500 fpm. The app can't "remember" this preferences, goes to the default mode. Maybe a great addition could be adding internal liner (1/2" and 1"). The ductulator can show both outside and inside duct dimensions. Also, the tabs for altitude and pressure drop are so wide! Was useful to have them narrow like others, eventually airflow, velocity and duct sizes could be wider for easy access.
★★★★★
Best duct sizing ever. thank you.
★★☆☆☆
Doesn't calculate velocity correctly for rectangular ducts. It is calculating velocity of round duct with equivalent diameter, not velocity in rectangular duct. They are not the same. For example at 500 cfm a 6×12 duct has a velocity of 1000 fpm not 1097 fpm.
★★☆☆☆
Not too much flexibility in terms of varying inputz and changing units. Also interface is not intuitive and hard to use.
