Just another helpful tool, instead of needing to buy a 3rd party weather app just for hourly updates, like I always have.
The weather app in iOS 5 has a new feature that lets you view the hourly forecast of the current day with a simple swipe of your finger. It’s a minor improvement that doesn’t compare with full-featured apps like Weather HD or Weather Bug Elite. But still, it’s a nice touch for those that prefer the simplicity of the built-in app.
It saves money, and space on the device!
