Which mobile operating system utilizes "Live Tiles" for real-time updates on its home screen?

The mobile operating system that utilizes "Live Tiles" for real-time updates on its home screen is Windows Phone. Live Tiles are dynamic tiles that can display live content, such as notifications, messages, or updates from apps, directly on the home screen. This feature allows users to see essential information at a glance without needing to open the app, making the interface more interactive and user-friendly.

Windows Phone introduced this unique approach to app icons, differentiating itself from other mobile operating systems. Each Live Tile can be customized in size and can represent various types of content, thereby enhancing the personalization of the device.

In contrast, other operating systems like iOS and Android use static app icons on their home screens, while BlackBerry OS traditionally employed a different layout without such dynamic elements. Therefore, Windows Phone's Live Tiles stand out as a notable innovation in the way users interact with their mobile devices.
