Apple has released watchOS 2.2 for all models of the Apple Watch, improving the Maps app and allowing multiple watches to be paired with a single iPhone. You can find the 120 MB update in the Watch app on your iPhone, in My Watch > General > Software Update. To update, the Apple Watch needs to be in range of your iPhone, connected to its charger, and charged to at least 50 percent. The entire process could take 30–45 minutes all told, so make sure you have time.
The most notable change is the Maps app, which has been redesigned to more closely resemble the Google Maps app. Now, instead of just displaying a map with your current location, it offers quick shortcuts to Home, Work, Search, and Nearby locations. This should make it a bit more useful on the Apple Watch.
Another new feature is that with watchOS 2.2 and iOS 9.3, you can now pair more than one Apple Watch to an iPhone. Switching between watches is automatic — simply unlock and raise one to activate it with your iPhone. It’s hard to imagine too many people needing this feature, but hey, when you have to choose between your yellow gold and rose gold Apple Watch Editions to match your outfit…
The watchOS 2.2 update also includes 18 security updates.
