Know you're getting sick before you feel it. Sick Watch monitors your overnight health signals – heart rate, HRV, temperature, and breathing – to spot the patterns that appear 1-3 days before illness symptoms. Based on research from Stanford and UCSF involving 63,000 participants, multi-signal detection can identify illness brewing with 82% accuracy, nearly 3 days before you'd normally notice. How it works: - Wear your Apple Watch to sleep - If you have existing sleep data, predictions start immediately - New watch owners get early predictions after 7 nights, full confidence at 14 - Get alerted when signals suggest your body is fighting something - Take action early – rest up, clear your schedule, boost your defences Features: - Four-signal monitoring (temperature, HRV, heart rate, respiratory rate) - Personal baseline (not population averages) - Automatic alerts when something's brewing - No iPhone required – runs entirely on Apple Watch - Privacy-first – all data stays on your device Requirements: - Apple Watch Series 4 or later - watchOS 10 or later - Series 8+ recommended for temperature monitoring One-time purchase.
