Fahrenheit – Weather and Temperature on your Home Screen ($0.99) by International Travel Weather Calculator is an impressive new weather app with something very clever to offer. It uses the latest technology to show the current temperature right on the home screen. Apple is notorious for not letting apps operate outside their guidelines, and this is especially true when it comes to the functionality of iOS. So how have the developers beaten the system?
The developers have found an interesting loophole. They are utilizing an app’s ability to display a notification number and are using it to share information with users. This is how they are able to show the current temperature from anywhere on the home screen, through the use of this notification number.
Aside from this outstanding feature, the weather app itself is actually quite impressive. It supports the use of the iPhone’s current location, but can also be given a specific city. Users can also add multiple cities to the app, there is no limit. The comprehensive weather information includes: rainfall totals, cloud cover, wind direction, and even sunrise and sunset times.
The app is, without a doubt, a full-fledged weather application. The only thing it seems to lack is live or even hourly radar pictures. There is an in app purchase that allows you to see hourly rain radar, and satellite maps, however this expires after only two days.
Overall Fahrenheit is an excellent weather app for bringing you all the latest information. But, if you’re located anywhere outside of the United States don’t worry, there is a Celsius version that offers the exact same features. Whether you are looking for real time weather updates on your home screen, or just a new weather app, this is a must have for any iDevice.
