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?

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.

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

I use this one more often than any other I have, It's great

Like it

I like it
But i wish i can lock friction rate
I hope in next version i can do it
