ASHRAE Psychrometric Chart for Android

Needs undo feature. Does not work well with Google Pencil; selecting a state point causes the point to move; must use finger to select points. Connecting points with a process line will not carry forward the airflow rate; must be entered by hand for each point. Mixed air points are static individual points that are not tied to the air streams that created the mixed air point, such that if the conditions change then the mixed air point must be recreated. Occasionally, when pinching to zoom one of the state points will move even though my fingers were not near the point; something similar to this happens a couple of times on the training video from Carmel. The point properties form is not visible after zooming, appears to be off screen. Wish List: Create state points based on process loads. Bottom Line: The app feels like a beta version for a psychometric chart program that had a very limited budget. In 2020 I expect software that is a bit more polished and more user friendly. And as one other comment stated, I would expect a little more from ASHRAE.

Does not print legend assigned colors with email.

has potential, but is buggy and has stability issues. Also, needs a screen where points can be directly entered by typing, and I dont see any way to easily compute attributes of process lines between points.

Please allow email output to show complete calculations uses for state points.

I expect more from an app with a ASHRAE label. Loaded this app on my Mobile 4G and cannot get a landscape display.
