Your cortisol curve is about to get a new running buddy: heart-rate data from your favorite wearable. In June, the Eli app pulls BPM readings from Apple Health, WHOOP, Oura, Fitbit, and Garmin straight into your Hormometer so you can see, in real-time, how spikes in pulse line up with surges in stress hormone.

FAQs
- Is this iOS-only?
Yes, for now. Android support is on the roadmap. - What if my wearable isn’t listed?
Tell us here, we prioritize new integrations by user demand. - How is my data protected?
When you connect a wearable, you give Eli permission to pull the heart-rate data that device already collects. That transfer isn’t end-to-end encrypted by Apple, WHOOP, Oura, Fitbit, or Garmin, but it only starts after you grant consent—and you can revoke that permission anytime in Settings → Integrations.
