DewPointHygrometer vs DewPtFm

DewPoint Hygrometer displays the dew point, air temperature, and relative humidity at your current location. The app is launched in the main window, and "Circle..." will be indicated in the status at the top of the screen. DewPoint Hygrometer establishes your location from GPS satellites, and then obtains the meteorological information that applies at the relevant co-ordinates. The display format for the retrieved information is: " pressure_mb, visibility_km, Rain Intensity, UV level". Details View will show up after press D button.

This app computes the dew point temperature and relative humidity from a wet bulb temperature, dry bulb temperature and barometric pressure. If a barometer is not available a guess of 29.8 inches of mercury will usually give a near enough result. Temperatures are in degrees Fahrenheit and pressures in inches of mercury. Uses a computation method suggested by the National Weather Service of the National Oceanic and Atmospheric Administration, USA.
