The Apple Watch is part smartwatch, giving you the ability to run apps and display notifications from your iPhone. It’s also part fitness device, measuring your heart rate, tracking workouts and — with the release of WatchOS 7 — it can now monitor your sleep, too.
With so many features and capabilities built into Apple Watch, it can be overwhelming as you try to make sense of why your watch has so many apps installed on it, or why Siri keeps randomly talking to you.
