## Description

Sleep Details uses Apple Watch data via Health (watchOS 10+) to deliver a daily sleep score and in-depth metrics such as sleep stages and times, heart rate, heart rate variability (HRV), respiratory rate, and SpO2 on Series 6+ devices. It supports viewing data on iPhone and on your watch, with Night Mode showing the most recent 4 hours of averages, and a two-week trend to spot patterns. The app prioritizes privacy – no data are collected from your devices.

Key features include tagging sleep with factors that affected it (like caffeine), adding detected or manual naps, watch face complications, morning notifications with last night’s score and duration, and a memory test to track cognitive impact of sleep. Track history, averages, and min/max values across all metrics. After the free seven-day trial, you can subscribe monthly or opt for lifetime access to unlock charts and tools. Terms link and support available.
