Can't open the apple watch app

Hey there karlypop11,

We're happy to help with this trouble you're having with the Watch app. First, we need to make sure the software on the companion iPhone is current. If you are not using iOS 14.3, get the steps to update here:

Update your iPhone, iPad, or iPod touch

Next, we'd like to have you unpair the Watch from the iPhone. Doing so will trigger a backup to the iPhone, so there's no worry of data loss. Follow the steps here to unpair:

Unpair and erase your Apple Watch

After unpairing, restart your iPhone:

Restart your iPhone

Once the iPhone has restarted, launch the Watch app. After the Watch app opens, pair the Watch back to the iPhone.

Let us know the outcome, and we can go from there if needed.

Have a great day!
