I Don't See the Watch App
The Watch app requires watchOS 4, an update Apple shipped in September 2017. If you're still running watchOS 1, 2, or 3 you'll need to update to install the free update through the Watch app on your phone (you can check this by going to the Watch app on your iPhone and then General -> Software Update).
If you're running a recent version of watchOS but Slopes isn't showing on the Watch, there are steps to try:
- Do you have auto-install enabled for Watch apps? Did it maybe not auto-install? Is it in the middle of installing? Head into the Watch app on your phone and scroll down to see if Slopes is available for install. As you scroll down you'll pass Apple's apps first, then currently installed third party Watch apps, then third party apps that have yet to be installed (and those in the middle of being installed). You should see Slopes in one of those last two sections and that'll give you a clue as to what is going on.
- I hate the cliched answer, but have you rebooted your phone and Watch? Many users say this solves the issue.
- If Slopes isn't anywhere in those lists, try deleting and reinstalling the Slopes iOS app from the App Store.
