Night Story turns your iPhone into a private window into the night. See detected snoring events, their timing and frequency, review an optional short clip, add a morning check-in, and discover patterns over time. With Apple Watch, view available heart-rate changes beside night events. History, Trends, Insights, Daily Factors, Weekly Summaries and the Personal Sleep Guide turn separate nights into a longer story. No account is required, and full-night audio is never stored.
