This is a worthless app.
Total waste or money
What did I just purchase
It’s an app that asks you what kind of duct for what pressure rating you want, and then it just tells you back what you just told it.
Response from developer
Hi, thank you for your feedback. Once you input the duct size and pressure rating, the app will list the acceptable duct construction and reinforcement options. Start by checking your input, and if the problem persists, let us know at welmurr@icloud.com
