Terrible Uses too much resources that it can not be used, uninstalled.
Great HVAC/R Industry App This is great for business owners, manufacturer's, installers, service techs and anyone else in the hvac/R Industry. It has business information and technical information. It even covers legislation! The app works well and Is easy to navigate. I always have trouble with the app every time I update it. I highly recommend it! Plus they have a paper version. I opted into receiving webinars from them and have found them to be quality and informative.
It is slow when it starts, some times the app do not responds.
Blows! Shuts down all the time!
Links to pdf files don't work.
Needs work The app hardly ever loads.
Added support for devices running Android 5.0, Lollipop.
