If you’re already subscribed to Clue Plus, you can still link your Clue account with Wellhub. Just go to the Clue page in your Wellhub app, activate the partnership, and then sign in to your Clue account.
Once your current Clue Plus subscription ends, you can then start using Clue Plus with your Wellhub membership. This will happen automatically. If you’re enrolled in auto-renewal, you’ll need to check in with your App Store or Google Play Store settings about when your current subscription ends.
