Mactories posted an article about Sun, a beautiful and simple weather web app for iPhone and iPad. Its free, and all you have to do is go to the page using Safari on your iPhone or iPad and add it to your home screen. Once installed, it will of course ask to know your location and that place will be the default. You can add three more cities, choose from Fahrenheit or Celsius, miles per hour, kilometres per hour, or meters per second, as well as color palette. If you swipe to the side, it will change cities, if you pinch the screen you can see info for all four cities at once. If you tap on a location, it will show a chart with projected temperatures and a ten-day forecast. Also, the icon will tell you the temperature of your current location. Really cool web app created by Jakob Henner.
