Duct guy
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.
Solid app, not quite 5/5
Decimal point
Response from developer
Hi David, thank you for leaving a review. It seems there was a bug on some iOS keyboards Canada region, preventing the app from registering the ‘comma’ decimal point. We fixed it immediately after your review; it should work after you update the app. Thanks for pointing this out!

Best duculator for IPhone
I use it everyday when measuring out

Review
Ductculator
Pretty useful
Response from developer
Hi, thanks for your review! By design, the duct size increment is 2" for sizes above 12", since odd sizes above 12" are less common. However, taking your review into consideration, we will add the option to increment by 1", in the upcoming update.
It’s ok at best
Response from developer
Thank you for taking the time to write a review! You can access the Sizing sheet by tapping the circular button at the bottom of the screen; There you can punch in duct size and adjust the CFM according to the desired Friction rate and Velocity (exactly like the classic ductulator). Hope this helps!
Don't be afraid to invest in this very useful tool.
Needs work
Response from developer
Hi, could you send us more info regarding the issue you are facing at welmurr@icloud.com? Make sure you include some screenshots and specify the device you are using.
Let me reverse lookup
Response from developer
Hi, thank you for your feedback! In the Sizing View, you could fix a duct size and then push the CFM up or down until you reach the desired Pressure Drop & Velocity. Hope this helps. If you would like to know more, or have any suggestions, feel free to email us at welmurr@icloud.com.
No Flex in duct calcs
Response from developer
Since a few users have requested ‘flex’ duct calculations, we started integrating this functionality in the next update. Edit: Ductulator latest update is now live! It features ‘Flex’ duct calculations. Thank you for your feedback!
Very Nice
Response from developer
It’s coming in the next update! Edit: Latest update is now live! It features ‘Flex’ duct calculations. Thanks for the feedback!

Hello, thank you for the kind review. You could not have timed this better; we have just released our latest update, which features 'Duct Edit' mode! If there are any features that you would like to see added, let us know at welmurr@icloud.com
Friction rate…
Response from developer
Hello, and thank you for your feedback! We tried replicating the issue you are describing, but all the inputs are working correctly. Would you send us some screenshots to welmurr@icloud.com, so we could look into them?
It’s a must have
