Smart clocks are advanced timekeeping devices that often connect to the internet and can perform various functions beyond just telling time. They typically feature digital displays and can show weather updates, calendar events, and notifications from smartphones. Many smart clocks also include voice assistants, allowing users to control smart home devices or ask questions hands-free. These devices can sync with other smart gadgets, such as smart speakers and smartphones, to create a cohesive smart home experience. Some models even offer sleep tracking and alarms that adjust based on sleep patterns, making them useful for improving overall sleep quality.
