As a rule, the iPhone, iPad, and iPod Touch do not support widgets, so most iOS weather apps just show you a cute picture of a sun or rainstorm and you actually have to start up the application to see anything else.

One developer has figured out a way to show you the current temperature on your home screen by using the notification system that has been around since iOS 3. Instead of showing you how may instant messages or friend requests are waiting for you, Fahrenheit sends an alert with the current temperature.

The number shows up in the upper right corner of the icon on your home screen icon and if you only want to know whether to grab your sandals or winter coat as you head out the door, that might be all the information you need.

If you actually open Fahrenheit, you have access to additional details ranging from current conditions to radar and forecasts.

Fahrenheit is available from the App Store for just 99 cents. It’s almost worth paying that much just to support the clever developer who came up with the idea of getting around one of the iPhone’s limitations by the available developer tools.

Of course, if you live across the pond, there is also a ‘Celsius’ app which offers an identical feature set.
