Dreamer is a smart sleep tracker built for Apple Watch. It analyzes your night automatically and gives you a clear 0โ€“100 sleep score every morning โ€” no manual input needed. Everything runs on your wrist. Dreamer reads data from Apple Health, scores your sleep using 11 metrics, and helps you understand what makes a good night. Duration, sleep stages, efficiency, heart rate variability, and more โ€” all combined into one simple number. LIMITED TIME: DREAMER IS COMPLETELY FREE For a limited time, Dreamer is available at no cost. No subscription, no in-app purchases, no catch. Get full access to every feature while this offer lasts. SLEEP SCORE A single 0โ€“100 score calculated on-device from Apple Health data. It combines duration, stages, efficiency, awake time, awakenings, sleep latency, and consistency. Recovery signals like HRV, resting heart rate, respiratory rate, and blood oxygen are used when available. Short nights are capped and missing data lowers the score โ€” so you always get an honest result.

Sick Watch

Read full description

Know you're getting sick before you feel it. Sick Watch monitors your overnight health signals โ€“ heart rate, HRV, temperature, and breathing โ€“ 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 โ€“ 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 โ€“ runs entirely on Apple Watch - Privacy-first โ€“ 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. No subscription. No ads. NOTE: Sick Watch is not a medical device and does not provide medical diagnoses. It is intended for general wellness purposes only. Always consult a doctor before making any medical decisions.
