HVAC mechanics have a new option when it comes to the standard paper pressure-temperature (PT) chart they currently carry. Honeywell offers a colorful display in which users can select a refrigerant and get all of the data they need to perform their tasks in the field. Using the touch screen, users can quickly calculate superheat and subcool averages to set a control from either their iPhone or iPad device.

App crashes immediately. Won’t even open. Used to work great. Used it daily and was very accurate. But now I can’t even look at the charts.
Great update. App shuts off now every time I have to try to select a refrigerant. Worked fine before the update. Oh well, pt charts aren't hard to find

Used to work until this last update, crashed instantly now on my iPhone X
