About Baseline

• Baseline is an iPhone app with Home Screen widgets built around Apple Health data.
• It helps you check readiness, sleep, HRV, steps, and activity at a glance.
• All calculations are done on-device. No account is required.

FAQs

• What does Baseline show?
  Baseline shows readiness, sleep, HRV, steps, and activity 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, steps, active energy, and exercise time 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?
  No. Baseline does not require an account and does not upload your personal health data to its own servers.
• How do I remove my data?
  Baseline stores its app state locally. You can revoke Health access in Apple Health or Settings, and deleting the app removes its local app data.

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.
