I am a retired Meteorologist recording my Weather observations every few hours. I have used this App for over a year now, and have found it to be very useful and indispensable. Highly recommended. 5 stars !

Good app, needs some detail resolved.

Good app, fast and clean, the layout needs to be a bit more logical though. For example name each calculation after what it provides you, not what you need to input. Wish there was a prefs pane for setting units, instead of changing units each time I recalculate which frequently leads to mistakes
