Not what I was looking for
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.

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. Update- Ductulator is used daily by thousands of professionals to size HVAC ducts for all applications, residential included; It is definitely not ‘just for fun’ although the intuitive user interface makes it fun to use! Cheers.

WHY WAS I CHARGED ??
Response from developer
Hi Christian, the app is not free; the amount you were charged was the app’s purchase fee as indicated on the App Store page (a one time payment). This part is handled by Apple’s App Store. You may still be able to apply for a refund through the App Store if you wish. Cheers.
