Thanks for the changes I really like this app. The only thing that is inaccurate is velocity on Regtangular duct. Type in 12x12 and cfm should match fpm and it does not type in 24x6 and even worse. I think it calculates off of equivalent round instead of actual rectangular size thanks
Not to bad With what I deal with this could be simpler but after you get all your numbers right it is helpful
In IP units it fails and calcs wrong for fpm x area = cfm. And as duct size increases answer gets worse. Took me more than 15 to realize now I'm :(
Hard to use When trying to scroll the slider move and change results. Can't see enough of the screen at once to be an efficient tool.
Very useful application I am always out in the field doing quick sizing of installed ductwork. With this application, I can double check the work of our contractors fast and easy. Accurate, too!
Great app to replace those low tech TRANE ductulators we have been using for too long.
1. Updated the user interface (UI) to better accommodate larger Android devices like the Google Nexus and other Android tablets.
2. Added a "tabbed" UI so can easily navigate the app
3. Added "Flexible Duct, Helix Core" duct material to database
4. Updated the Android engine so that it works on all of the latest Android devices
