It's good and easy. Really needs the ability to use odd numbers though. That would make it perfect. Edited

Disappointed, i was expecting it to be more flexible with the Units, but i was stuck with m3/hr, an i need to use L/s, so if I'm gonna use this app I would have to do so many unit conversion for a ducting design of a building. Edited

Hello, thank you for the feedback! Air flow volume in L/s is coming is the next update! If you have any further suggestions, feel free to contact us!

This is not what is shown in the picture. It is nothing but just numbers. It does not have the adjustable diagram at all.

Pretty much worthless. Can't enter dimensions without a CFM measurement. Measuring the duct for system replacement (usually inoperable) I want to know what it can handle at WC

Hi Jason, thank you for your feedback! Just like when using the traditional ductulator, you can set the existing duct dimensions, then tweak the air flowrate till you reach the desired friction rate or velocity limit. That would give you the maximum air flow that the duct can handle for the given friction/velocity. Hope this helps!

Completely unnecessary. A shame that we value using our brains so little that we wish to open source a skilled trade that requires training and field experience to understand. Every certified tradie can do the math in their head. Useless.
