NapBot - Auto Sleep Tracker

NapBot is an automatic sleep tracking and analyzing app for iOS and watchOS devices. It uses on-device machine learning to detect and understand your sleep, delivering automated sleep tracking, detailed sleep-phase analysis (deep vs light), environmental sound exposure insights, and a sleep heart rate summary.

Pro features include Sleep History and Sleep Trends, offering full sleep history overviews and trend analysis to understand how habits influence your rest. The app reads heart data from the Health Data Store populated by Apple Watch and requires an iPhone with the Health app. Subscriptions are auto-renewable, with management available in Account Settings. Privacy details and terms are provided by the official NapBot policy page.
