The Apple Watch serves as a companion to a user's iPhone, and can display both past and incoming Snapchat notifications on a person's wrist. Although Apple's smartwatch has become more powerful and self-sufficient over the years — gaining processing power and features — it still can't replace an iPhone. Some applications don't even support watchOS, and need to be accessed via a paired iPhone. But users can view their iPhone's incoming notifications on their Apple Watch even if the sending application doesn't have a native watchOS app. That includes Snapchat, the popular social media platform centered around sharing photos and videos.

By opening the Apple Watch app on a paired iPhone, users can make sure the Snapchat app is allowed to send notifications to their smartwatch. From the app, tap the 'Notifications' tab in the middle of the 'My Watch' page. Scroll past the system-wide settings toggles and the tabs for Apple's native watchOS apps.
