Not able to open the fitness app on my iPhone. Says I need to set it up in my watch but it is.

Hey Redra,

We'd be happy to help out. Sounds like you're having issues using the Fitness app on your iPhone since it's stating it's not set up on your Apple Watch.

This could be indicative of a communication issue between your iPhone and Apple Watch, so to get started restart both devices. If that doesn't help out, please unpair and erase your Apple Watch and then set it back up again with your iPhone using these steps:

Unpair and erase your Apple Watch - Apple Support

How to unpair your Apple Watch from your iPhone

1. Keep your Apple Watch and iPhone close together as you unpair them.

2. Open the Apple Watch app on your iPhone.

3. Go to the My Watch tab and tap All Watches.

4. Tap the info button  next to the watch that you want to unpair. 

5. Tap Unpair Apple Watch.

6. For GPS + Cellular models, choose to keep or remove your cellular plan. 

• If you want to pair your Apple Watch and iPhone again, keep your plan. 

• If you don't want to pair your Apple Watch and iPhone again, remove your plan. If you aren't going to pair with a different watch or iPhone, you might need to contact your carrier to cancel your cellular subscription. 

7. Tap again to confirm. You might need to enter your Apple ID password to disable Activation Lock. Before erasing all content and settings on your Apple Watch, your iPhone creates a new backup of your Apple Watch. You can use the backup to restore a new Apple Watch. After your Apple Watch unpairs, you'll see the Start Pairing message.

8. Set up your Apple Watch again.

We hope this information helps out.

Take care!
