Good for duct sizing
Where’s the option for flex duct?
Not happy with my purchase
GREAT APPLICATION
I've been using it for many years, my go to every day.
Really mot good app .
Calculation are not acure , not integral proximity in calculations
Subscription
Do I have to pay monthly subscription for this app or just one time pay at the start?
Can’t change velocity below 100 m/s
Still cant set the air velocity below 100m/s
Almost perfect… but not quite there.
This thing is great. only 2 things would make it perfect. 1) Flex duct sizing. 2) multiple friction rate fields, so you can select both your return AND supply friction rates at the same time and see output of both. plus have those fields be lockable so you can’t change them by accident. If these changes were made, I would buy this AGAIN and likely so would every consultant in my company.

Better than cardboard Ductulator
It’s a little difficult to get used to the way things work at first, having only used the rotating cardboard Trane ductulators in the past, but once you get used to it it is much more accurate and far easier to obtain correct sizing for very specific lengths and widths of duct.
Not accurate
I was trying to find an app for the convenience of not carrying several sliders around in a bag, I just have everything in one place. But the interface isn’t easy to use or quick, and non of the numbers are adding up to any duct calculator I have or have access to. I can’t trust any of the numbers and I can’t use something if I can’t trust it.

Good application for HVAC Duct work
Good app
Great app.
I really like the dial format for selecting duct sizes.
A must have
This is an excellent tool for on the job calculation. It’s a must have.
Problems since update
Latest update seems to be causing velocity errors, 132 l/s on a duct size of 200mm dia should jot be coming up as over 40m/s ?? Please can this be rectified as was a great app before the update
Response from developer
A fix for the velocity display issue has been submitted and approved by Apple. The update should be rolling out soon. You can contact us directly here: https://www.pheinex.com/contact/

Limited
Not user friendly. Only able to develop some calculations based on single sections of distribution systems. Don’t try to find out existing conditions using this format because duct sizes change as variables are imputed. Very frustrating.
Best on App Store
Best duży Calculator in the App Store, easy to use, intuitive. Don’t waste money on anything else.
Useless app
If I could give this app less than one star, I would! I’m out the money for the app. It’s unusable! Lesson learned!! Look elsewhere. I deleted app sent an email, no response!!!

Finally received an email from developer. Asking if I am having problem using the App. They just don’t get it! The app does not work as described!! I asked for a refund, doesn’t look like that will happen! Again, lesson learned! DON’T PURCHASE THIS APP, IT’S USELESS!!!

So less functions and so expensive
Nothing to say
Weak
Weak app
Top one
I use this one more often than any other I have, It's great
