Appy Weather is a popular Windows Phone weather app that presents weather forecasts in somewhat of a personal nature. With a minimalistic design, the weather app does offer the nuts and bolts of your forecast but also offers a comparison of upcoming weather conditions to what you are experiencing now (e.g. temperatures will be much colder than today, etc.)
Appy Weather received a significant update last month that delivered lockscreen support and the ability to use Bing images or custom photos as your lockscreen wallpaper. Since that update, the Windows Phone app has received six updates with the most recent update pushing out today taking the app to version 1.2.2.
