Samsung Galaxy Phones
Using a Samsung smartphone, you'll get the best experience. It pairs quickly and all of the needed apps are on your phone.
Plus, Watch 4 can use all of its fancy health features with a Galaxy phone, like taking an ECG or figuring out your body fat percentage.
At least you can get Google apps
It's not all bad news, though. Wear OS provides the Play Store and you can download apps like Google Maps and Google Pay.
Oh, and you're stuck with Bixby
Despite pretty much everyone hating it, Samsung still includes Bixby on the Galaxy Watch 4.
