Finally understand your gut.
The wearable for gut health and nutrition, designed to help you see your own patterns. No food diaries, no guesswork, just your data.
Suna meets you where you are.

Food response
Continuous, real-world response data instead of a one-off lab snapshot.

The organ that controls 70% of your immune system and produces 90% of your serotonin.
Suna changes that.
Wear it. Forget it. Learn everything.

How Suna compares
Three ways to learn about your gut. Only one of them captures it as it happens.
What it captures
The digestion process: sounds, heart rate response, temperature, motion.
The output, photographed at the bowl.
The microbes living in stool.
How often you learn
Continuously, throughout the day.
Only when you sit on that toilet.
Once. Re-test costs more.
Time to insight
Instant, in the app.
A few minutes after the visit.
Two to six weeks.
Where it works
Anywhere you are.
Your toilet, at home.
At the lab, after you ship a sample.
Food to symptom in real time
Yes, within minutes.
No. Hours later, by inference from output.
No. A single frozen snapshot.
Sleep, stress, workouts in the picture
All of it, woven in.
Not measured.
Not measured.
A one-off test shows what's there. A toilet camera shows what came out. Suna shows what's happening.
