Nightmark turns the sleep data your Apple Watch already collects into a morning summary: sleep-stage breakdowns, heart rate and HRV trends, and vitals analysed against your own baseline.
In the evening it switches to bedtime recommendations tuned to your patterns. Everything runs on your iPhone, so your health data never leaves the device.
Features
What it does well.
Morning Report
03Morning insights
Wake to last night's duration, a sleep-quality score, and how you compare to your own baseline.
Sleep stages
Splits each night into Deep, REM, Core, and Awake from your Apple Watch, so progress and gaps stand out.
Health vitals
Tracks heart rate, HRV, respiratory rate, blood oxygen (SpO2), and wrist temperature, each correlated with sleep quality.
Long-Term Trends
01Insight engine
Learns your patterns over 14 days, then surfaces trend shifts, consistency streaks, and workout-sleep correlations.
Guidance & Recovery
02Evening mode
After 6 PM, switches to bedtime recommendations tuned to your patterns, goals, and recent trends.
Jet lag recovery
Detects time-zone changes when you travel and gives recovery guidance to help you adjust faster.
