Somnus: AI Sleep Tracker

What if your sleep data could tell you exactly what to change?

Somnus doesn't just track sleep — it finds hidden patterns between your daily habits and sleep quality, then gives you a system to prove they work. All analysis runs on-device using Apple Intelligence. Your health data never leaves your phone.

DISCOVER WHAT DRIVES YOUR SLEEP
Somnus analyses 25+ health signals — sleep stages, heart rate, HRV, steps, exercise, bedtime consistency, and more — to find the specific habits that move your sleep score. Not generic tips. Your patterns, from your data.

- Personalised insights backed by statistical evidence
- Causal pattern detection: find what improves your sleep, not just what correlates
- Confidence levels show how strong each signal is
- Categories: Sleep, Activity, Recovery, Circadian, Stress

RUN SLEEP EXPERIMENTS
Found a pattern? Test it. Create structured plans to prove whether a habit change works — with measurable before-and-after tracking.

- Set targets like "bed by 11 PM" or "run 3x per week"
- Automatic daily hit/miss adherence detection
- Compare sleep scores on target nights vs off-target nights
- AI-generated weekly reviews summarise progress
- Track record calendar, streaks, and impact analytics

SLEEP SCORE BUILT ON SCIENCE
Your nightly score draws from four research-backed pillars: duration, continuity, regularity, and sleep architecture. Apple Watch stage data adds deep sleep and REM analysis.

- "Vs Usual" comparison for every night
- 7, 30, and 90-day trends
- Perceived sleep slider: how you feel vs what the data shows
- Tap any night for a full breakdown
