If you have any health concerns, please consult a doctor or a qualified healthcare professional. • Testing Principle Photoplethysmography (PPG): The phone's flash emits green light and other specific wavelengths that penetrate the skin. The camera captures periodic changes in light absorption caused by blood flow during heartbeats, converting these into electrical signals to form a PPG curve. Algorithms then calculate heart rate from this curve. Heart rate variability (HRV) is extracted from the curve's beat‑to‑beat interval data. Finally, by combining heart rate and HRV variations with a model trained on population stress data, the system infers stress states. • Data source reference：https://pubmed.ncbi.nlm.nih.gov/28288955/ 【Subscription Information】 ‑ Subscription fees will be charged to your App Store account upon confirmation of purchase. ‑ Subscriptions will automatically renew and be charged unless auto‑renewal is turned off at least 24 hours before the end of the current subscription period. ‑ Any unused portion of a free trial will expire upon purchase of a premium subscription. ‑ Manage or cancel your subscription in Account Settings.
