Useful and accurate App
The app provides fairly accurate results (verified with a Mollier h-x-chart). I use it to adjust the supply temperature of my heat pump in summer without the risk of condensation. For this the app is top (much more conveniant and faster than with the h-x-chart). € 1,99 only for the input option in degree Celsius (instead of Farenheit only) and the conversion also to Kelvin I feel high. With € 1,- it would be 5 stars.
