Weather:
Helios Clock 2 can now display the external temperature at your location. You have two choices of weather service: Yahoo Weather or your own Netatmo Weather Station.
To use Yahoo Weather, all you have to do is to agree to the use of the localization service (gps). The gps will only be used once per hour when the application is in used.
For the Netatmo service, of course you need to own your own Netatmo Weather Station. You will also need to give your Netatmo username and password, but only once to request authorization from the Netatmo servers. Your password and username are never saved in the application preferences.

* To be able to know the time of sunrise and sunset, Helios Clock needs the GPS coordinates of the iPhone.
