Ductulator
Simple duct sizing app, both English and Metric units
Users can change between I-P and S-I units by tapping the units, on the right.Duct sizes can be obtained based on either maximum friction or velocity. Tap on the values for velocity or friction to switch between calculation methods.Calculations are based on standard air 0.075 lb/ft3 (1.2 kg/m3) in clean galvanized steel duct.Your feedback is much appreciated.

Simple, fast and everything you need if you don't have a duculator with you. Seen the bad reviews, if you have enough experience everything you need is in the app
Love this app since im in the HVAC business
Not worth a dollar. Its literally just plain and bare calculation. You punch in CFM and in/100ft and it tells you one size round duct and 2 box duct sizes. Where's the calculation for how many rooms the house has? Where's the explanation and/or education behind CFM's nd what not? The only reason I gave it an extra star is because its a fast calculator.
I was hoping to find a way to find alternative duct sizes, but the only option I get is to choose a CFM, out on the field you don't have that luxury.
Complete pile of junk
This is great for new construction hvac systems
A really simple and productive app. Great for making fast duct design decisions
Wrong calculations bad app I make several tries to check it was wrong.
feels like its missing more options or selections.
Good
