About Baseline

• Baseline is an iPhone app with Home Screen widgets built around Apple Health data.
• It helps you check readiness, sleep, HRV, heart rate, steps, activity, and workouts at a glance.
• Core calculations are performed on-device, and no Baseline account is required.
• Optional AI Insights is off by default and sends a minimized aggregate summary only after you opt in and request an insight.

FAQs

• What does Baseline show?
  Baseline shows readiness, sleep, HRV, heart rate, steps, activity, and workouts using Apple Health data and widgets designed for quick check-ins.
• How is readiness calculated?
  Readiness is based on sleep, heart rate variability (HRV), and resting heart rate compared with your personal baseline.
• Why does the app say "Building baseline"?
  Baseline needs enough recent Health data to build your personal baseline. After you have several valid days of data, readiness becomes more stable.
• Why are some metrics missing?
  Missing values usually mean Apple Health does not yet have enough data for that metric, or Baseline has not been granted permission to read it.
• How do I enable Health access?
  Open Baseline, allow Health permissions when prompted, then make sure sleep, HRV, resting heart rate, heart rate, steps, active energy, exercise time, and workouts are enabled.
• Why is the widget not updating?
  Open the app once after granting Health access, wait for the latest data to load, then re-add the widget if needed. Widget refresh can also depend on iOS background refresh timing.
• Why is my HRV unavailable?
  HRV depends on Apple Health data from your device or Apple Watch. If Health has no recent HRV samples, Baseline cannot show a current HRV value.
• Does Baseline sync my data to the cloud?
  Core health calculations and widgets work on-device without a Baseline account. If you explicitly enable AI Insights and request an insight, Baseline sends a minimized aggregate summary to its Supabase-hosted backend and OpenAI. It does not send raw HealthKit samples, GPS routes, source names, or device names.
• How long are AI Insights records retained?
  AI request and response records, hashed identifiers, and related operational diagnostics are retained for no longer than 90 days.
• What happens when I disable AI Insights?
  Disabling AI Insights stops new requests and clears locally cached AI content. It does not automatically delete records created by earlier requests.
• How do I remove my data?
  You can revoke Health access in Apple Health or Settings, and deleting the app removes local app data. To delete AI Insights server records, use the deletion option in AI Insights settings. If that option is unavailable, email x_feedback@hotmail.com for assistance.

Known Issues

• If widgets appear stale, open the app and let it finish refreshing after Health permissions are granted.
• If sleep or readiness looks incomplete, check whether Apple Health has enough recent sleep, HRV, and resting heart rate data.
• If a metric stays unavailable, confirm the related Health categories are enabled for Baseline.
