Help & FAQ

What is this?

Couple Health Sync links your health data with a partner's so you can see sleep, steps, and heart trends side by side - not just your own number in isolation. It's a web app, so there's nothing to install beyond your regular Apple Health or Fitbit setup.

Getting started

1. Sign in - enter your email on the home page. There's no password; we email you a 6-digit code instead.
2. Link with your partner - from the Partner page, invite them by email. Your dashboard unlocks once you're both linked.
3. Bring in your health data - from the Import Data page:
   • Apple Watch / iPhone: open the Health app → your profile icon → Export All Health Data, unzip it, and upload the export.xml file it contains.
   • Fitbit: connect your account directly - no file needed.
4. View your dashboard - today's numbers, a 7-day comparison, and longer trends, both combined and side by side.
5. Download it as a PDF - the Dashboard page has a Download PDF button that saves today's stats and all four charts as a report you can keep or share.
6. Explore Analytics - a deeper set of charts (sleep stages, heart rate, activity, and more) covering sleep, activity, heart & recovery, mobility, correlations, goals, and predictions. Charts tagged Live use your real imported/synced data; charts tagged Sample data show what's coming as we add more data sources - never your actual numbers.

Supported devices

Apple Watch / iPhone (via the Health app's export) and Fitbit (via direct account connection) are supported today. We don't yet support other rings or trackers - if that changes, it'll be listed here.

Is it really free?

Yes - sign-in, linking with your partner, importing your data, the dashboard, and PDF downloads are all free with no paid tier.

What about my data?

Only you and the partner you explicitly link with can see your health data - nothing is shared publicly or with anyone else.
