watchOS 7 is here and it comes with a bunch of impressive new features and changes that really make the Apple Watch one of the best smartwatches out there. We've been playing around with the watchOS 7 developer beta, and we've discovered some cool new hidden watchOS features. So here are all the watchOS 7 features you should know about.

This is the flagship feature of watchOS 7. Your Apple Watch can now track your sleep. Plus, it can help you unwind before bed so you can fall asleep easily. Sleep tracking is one of the features that most people really wanted the Apple Watch to get. I had my reservations, and I still do. However, it cannot be denied that the feature works really well.

You need to enable this feature manually, so you can check out our guide on how to enable sleep tracking in watchOS 7.

Another cool feature in watchOS 7 is hand washing detection. While still a nice feature, it makes even more sense in today's scenario. Once you've enabled hand washing detection on your Apple Watch, your watch will detect when you wash your hands. It then starts a 20 second timer complete with haptics and sounds to let you know when you've washed your hands for at least 20 seconds.
