Free elsewhere
You can find this same exact app for free with the Johnstone supply app. So save your $6.99
Very nice!
This app is very good. Wish I had it when I did A/C service work. Electronic ductilator ++
Works great.
You should see the eyes of an engineer when I pull out my phone and use this app to show him that I can change the size of his duct correctly because of a beam the engineer "missed" when designing the system. The best is when I go into a home and show the owners why my competitor installed too small of ductwork for their top of the line a/c unit.

Keep looking
Very user unfriendly. I hate it.
Best Ductulator You Can Get!!!
This is hands down the best ductulator you can get. The variety of options allow you to tweak whatever design conditions you would like. Waiting for a just now recommended upgrade for a total friction loss option where you could put together an entire system in order to size a blower.
It is a simple toys , not professional
Not a good value,if you try cook you will see a big difference
Nice and handy!
Just learning to properly size ducts using Manual D, only complaint is the list of materials doesn't include fiberglass duct board
Great
Finally an app I don't regret buying
