Deemed an essential iPad and notable iPhone weather app, Weather+ has already proven itself to be a great source of information, all wrapped up in a beautiful and easy to use interface. Now, with the release of v2.0, the app is even more visually appealing, quick to respond, and simple to manage.

As part of the beautification process, ITWC has upgraded the background videos to an HD resolution and tweaked the layout of some of the widgets. Not only were the videos improved, but some were even changed for what’s hoped to be for the better.

The small UI tweaks include moving the date display to immediately below the time, reducing the tint of the clock widget except behind the sky condition and apparent temperature display, swapping the locations of the humidity and precipitation display, reducing the tint on the upper portion of the hourly forecast, and fixing the five day forecast temperature display.

Progressing from the discussion of visual to functional changes, Weather+ v2.0 makes switching and deleting locations as easy as possible. Beyond swiping left or right to change locations, swipe upwards on iPad or double tap on iPhone to show the locations manager. At that point, you can either tap on a location to make it active or tap the “x” to remove it.

Overall, good enhancements, however, a higher image quality for the user interface elements wouldn’t hurt. In fact, that would probably be one of the few final improvements I can come up with. As a very final note, ITWC has already released Weather+ v2.0.1 to address some update process problems experienced by some customers.

Weather+ is a universal app compatible with iPad, iPhone, and iPod touch running iOS 4.3 or later, and available in the App Store for the limited time sale price of $0.99.
