AtEase · HRV & Recovery

AtEase measures heart rate variability (HRV) with your Apple Watch or your iPhone camera, and shows how recovered and how stressed your body is right now. [ONE TAP, ONE MINUTE] Start a measurement in the app and your Watch mirrors the progress, or start it directly on the Watch. [NO WATCH? NO PROBLEM] Cover the camera with your fingertip and AtEase reads HRV from your pulse — no extra hardware required. [TWO MEASUREMENTS FREE] Try the full experience twice without subscribing. Watch, camera and mindful breathing share the same two measurements; upgrade only if it earns a place in your day. [EIGHT METRICS, SHOWN BY SOURCE] SDNN, RMSSD, pNN50, Mean NN, MxDMn, Moda, CV and average heart rate, with plain-language explanations and reference ranges. Daytime Watch readings now derive RMSSD, pNN50, Mean NN and more from the heartbeat series; camera measurements provide full beat-to-beat data. Official values and estimates are labeled by source, and missing metrics are never inferred. [TAGS] Label each measurement — morning, after a run, after coffee — then compare the same situation over time in Trends. [SLEEP RECOVERY] Combines genuine overnight beat-to-beat data with sleep stages to provide a wellness recovery score when essential data is available. When data is insufficient, no score is invented. [TRENDS AND YOUR OWN BASELINE] Trends from 1 to 90 days, distribution and time-of-day patterns, judged against your normal rather than against someone else. [IT LIVES IN HEALTH] Results are written to the Apple Health app and sync across your devices over iCloud, so your history is always there. [EXPORT] Members can export a PDF report or a CSV sheet, for their own records or to bring to a doctor. [WIDGETS] Home Screen, Lock Screen and watch face widgets — your latest SDNN without opening the app. [ONE DAILY REMINDER] A single nudge at a time you choose, with your latest HRV and last night's recovery. Turn it off or change the time anytime. [SOFT, TACTILE INTERFACE] Follows your text size, full Dark Mode support.
