Undercurrent helps you notice changes in your Apple Health data over time. YOUR RECENT PATTERN Compare three recent consecutive observation days with at least seven earlier days in your recent history. Resting heart rate, HRV and sleep can contribute. View recent and usual averages, a 14-day chart when available, and the evidence behind the summary. Missing observations are not invented. TODAY'S FOCUS A short next step helps put the pattern in context. Changes do not identify a medical cause. When history is incomplete, the app shows what is still needed. EXPLORE YOUR DAY Browse available recovery, sleep, daily rhythm and health trends. Data availability depends on your Apple Health records and devices. APPLE WATCH The companion Watch app displays the personal trend and focus calculated on iPhone. Open Today on iPhone to refresh, then use Sync iPhone on Watch. A watch-face complication provides a shortcut to your latest pattern. Old or missing snapshots show an update prompt. PRIVACY No account required. Processing takes place locally. Your trend summary syncs between your paired iPhone and Apple Watch; no developer-operated cloud service or advertising tracking is used. Undercurrent provides general wellness information, not medical advice, diagnosis or treatment.
