You can now see what apps are available for the Apple Watch, even
if you don’t have one of the devices. Just open the Apple Watch
app on your iPhone, which comes with the latest iOS update, and
you can browse the available apps.
Certainly interesting that there are already a few thousands of these. But it’s worth noting that none of these are actually apps that run on the watch itself. They’re extensions that run on your iPhone and display on your watch over Bluetooth.
