Every Day Duct Sizing Tool

I use this every day all day, no other duct calculator app compares to the simplicity and accuracy of this app. I hope this never goes away…

Please don’t waste your money

Simply Rubbish
I don’t know why apple let them sale this kind of apps in App Store

Doesn’t Work On My iPhone 7

For some reason the app doesn’t show all of it’s functions that are advertised. Pretty much useless on my iPhone 7

Horrible app

Do a favor to your self don't buy this app is just a waste of your time.

Absolute ripoff

Doesn't do anything. A useless toy

Not worth the storage

This app is so basic and so simple it is not worth taking up any storage on your device. Let alone actually paying for it.

Not what you think stick to the cardboard version you always used its way off I give it half star

Very Basic

Doesn't allow you to enter a rectangular duct size, it does provide various sizes based on input criteria but that's not much help if you are working with already installed duct.

Useless

This app is another fail for the hvac apps

Good easy and ok

Facile à utiliser

Worst app ever

There's only about ten duct sizes I just got robbed.

Tech man

How do you determine between flex duct vs. hard pipe? This app needs lots of improvements. Good for a novice maybe. Should be able to select duct size (flex or hp ) and get aprox. Cfm based off length of run. Simplify your processes.
Good start.

Very accurate and helpful to use in the field, also saves time compared to the wheel.

Probably great for engineers but not very helpful for tradespeople.

More duct sizes, please?

I wish there were more duct sizes to choose from or a way for the user to input the duct size.

Awesome app!!

Must have for out of the office. Great job. Really helpful.

Excellent App for quick sizing

Excellent for quick sizing and decision making, well worth the purchase. Only one constructive suggestion the ability to limit the list of rectangular sizes by aspect ratio 1:1, 3:1 , etc
