Great app for a beta


I'm sure this will be a work in progress but a couple things to improve the usability.

1. Offer portrait mode when using the calculators.
2. Allow the friction rate selection in duct sizing.
3. Have a "Quick" duct sizing option, this way we don't have to see unnecessary fields that we aren't using.

Best HVAC app out

If Trumps Mouth Is Moving

I've downloaded numerous HVAC related troubleshooting apps over the years and this is the best one I've found. Even if you think you already know the answer, it's always nice to get confirmation. Especially good for new techs learning the fundamentals. It covers lots of ground and is an all around great app for anyone in the trade.

Great job! Thank you!

We have used your hard version of SuperCool since 2012. But now we are super pleased to have all this information right on our phone! The portrait mode would helpful as others have mentioned.
Thanks a lot for making the app!
