Not what I need
This app should be free, it says duct sizing. It only tells you what velocity and CFM a duct can do. I want my money back.
BEST D**N APP OUT THERE
You couldn’t find a better app for adjusting duct sizes and just overall use

Very helpful
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.

Response from developer
Hi, thanks for your feedback! The air flow-rate that could go through a given duct size varies depending on the friction rate or velocity you wish to set as limit. Thus, in ‘Ductulator’ mode, you can set a duct size and then check which CFM yields the Friction/Velocity limit you want; this would be the value you’re looking for, just like using the traditional ductulator! Hope this helps.
