Suna 101
What is SUNA?
SUNA is an AI-native wearable for gut health and nutrition — with intelligence across sleep, metabolism, cycle, and recovery. Your wearables track sleep, exercise, and steps. None of them track your gut. SUNA does — and connects it all together.
Health Domains
| Domain | What SUNA Provides |
|---|---|
| Gut Health | Daily Gut Score, real-time digestive state, meal response tracking |
| Sleep | Sleep staging, overnight recovery scoring, sleep-digestion correlation |
| Metabolism | Recovery readiness, energy insights, metabolic state |
| Cycle | Menstrual cycle phase tracking from temperature patterns |
| Recovery | Optimal windows for meals, training, and sleep based on your current state |
| Activity | Exercise-digestive correlation, activity context for scoring |
SUNA App (Available Now — works with Oura, Whoop, Apple Watch)
Connect your existing wearable to unlock cross-domain health intelligence:
- Meal logging — AI-powered nutritional analysis with macros, micros, and individual food breakdown
- Daily Gut Score — a 0-100 composite score combining overnight recovery, fasting patterns, meal regularity, and circadian alignment
- Sleep & Overnight Score — sleep staging and how your sleep quality affects next-day digestion and recovery
- Digestive State — real-time tracking of your current digestive phase
- Optimal Windows — personalized timing for meals, training, and sleep based on digestion, sleep, and HRV
- Cycle Tracking — menstrual cycle phase detection from temperature and physiological patterns
Scoring requires 48 hours of data to calibrate to your personal baseline.
SUNA Patch (Shipping Q1/Q2 2027)
A 7-day adhesive patch worn on the abdomen. Adds proprietary sensing capabilities that no wrist wearable can provide — including gut acoustics, sleep staging, abdominal temperature, and core-body physiological monitoring. Unlocks the full depth of every health domain above.
How Scoring Works
The Daily Gut Score (0-100) is a composite of four components. Each carries a contribution label — positive, neutral, or attention — so you know what to focus on.
| Component | What It Reflects |
|---|---|
| Overnight | How your overnight recovery affects gut readiness |
| Fasted Ratio | Balance between digesting and resting states |
| Regularity | Consistency of your eating patterns |
| Circadian | How well your eating aligns with your body clock |
