"Exploring the Enhanced Stocks App and Fourth Beta of watchOS 10 for Apple Watch"
The Stocks app on the Apple Watch has been redesigned in watchOS 10, offering a new user interface and a richer experience. The app now provides more information at a glance, including price change, percentage change, and market cap. Users can switch between day, month, and year performance charts, and easily add stocks to their watchlist. The app syncs between the Apple Watch and iPhone, and continues to use Yahoo for its data.
