Did you know that you could hail an Uber using your Apple Watch? No? Well it doesn't really matter anyway, because the Uber Watch app has effectively been discontinued, according to Apple Insider. If you try to use it, a message pops up asking you to switch the mobile app instead. It further states "we no longer [sic] supporting the Apple Watch app. Sorry for the inconvenience," with a crying emoji to drive the point home.
The app has yet to be pulled from the Watch App Store, but all you'll get is the error message if you try to use it. When it did work, it let you hail a ride, see the status of your request, and show the location of the vehicle. More advanced functions like fare-splitting were reserved for the smartphone app.
The grammatically challenged message suggests that the app may have been pulled with some haste, though neither Uber or Apple have commented. The App Store listing (above) touts the app as a way you can leave home without your smartphone and still hail a ride, provided you had a cellular-enabled Watch. To be fair, Uber also pulled its WearOS app back in 2019, likely due to a lack of usage.
