About Ductulator - Duct Sizing
This is a much faster and versatile equivalent of the duct sizing charts provided by top HVAC manufacturers.
Get a range of suitable duct sizes by inputting either the maximum friction rate or maximum velocity. Duct sizing for both rectangular and circular ducts. Tap on the values for velocity or friction to switch between calculation methods.
Users can change between I-P and S-I units by tapping the toggle switch at the top.
The detailed sizing mode allows the Engineer to adjust the duct dimensions and air flow rates, while checking the resulting friction rate and velocity which update automatically. Detailed sizing mode is typically used to analyse existing duct systems.
Calculations are based on standard air 0.075 lb/ft3 (1.2 kg/m3) in clean galvanized steel or non-metallic flexible ducts.
Any feedback is welcome, and will be the basis for future updates.

Not what I was looking for
Update- I got your email. I understand the way you have the app set up I just didn’t understand it before I bought the app. The function of your app is pretty much pointless for anything I need it for. If I want to size a traditional residential HVAC duct system this does not help. Your app mostly seems to be used to figure out numbers just for fun. Who cares what the velocity of 500 CFM going through 6 inch flex? You can’t get 500 CFM through 6 inch flex anyway so why would you want to know that number? End Update. You need to be able to pick 6 inch flex and then the app tell you how many CFM can go through that. The way this is set up now is just silly. I like the idea you can get velocity, but you need to know how many CFM goes through all the different sizes. Now I have to buy another app.

WHY WAS I CHARGED ??
I downloaded the app for free then was charged recently for $4.26 when I never signed up for a subscription or anything. The app is a scam I guess ?
