Swallow the capsule
A 12mm capsule, about the size of a large vitamin. Swallowed with water, like any other pill — no procedure, no sedation, no wearable to strap on.
Run a Session
Over two to four days, the capsule travels the length of your GI tract — stomach, small intestine, colon — sensing the whole way and passing naturally at the end.
Passive sensing, not logging
No food diary, no manual entries. The capsule continuously captures pH, temperature, motility, and pressure signals and streams them over Bluetooth to your app.
Get your Gut Score
Your app turns raw sensor data into a daily Gut Score and personalized trigger maps — which foods drove which symptoms, and when.
Most gut-health tools measure the output — a photo of the bowl, a stool sample shipped to a lab. Voyana measures the process: the pH, pressure, temperature, and motility of digestion as it actually happens, from inside the GI tract.
Four signals, one continuous read.
pH
Tracks acidity as the capsule moves from the stomach through the small intestine and colon — a marker tied to digestive efficiency and inflammation.
Motility
Measures how quickly (or slowly) the capsule transits each region of the gut — the clearest proxy available for regularity and transit time.
Temperature
Subtle temperature shifts along the GI tract can flag inflammation or irritation in specific regions.
Pressure
Captures contractions and mechanical activity — the physical signature of digestion in motion.
A well-established category, not a novel risk.
FDA-cleared since CorTemp
Ingestible sensors have been an FDA-cleared category for over 37 years, starting with the CorTemp temperature capsule.
Devices used safely
More than five million ingestible sensor devices have been used safely across clinical and consumer settings.
Passes naturally
The capsule is not retained or retrieved. It completes its Session and passes naturally, like undigested fiber.
Comparable to a large vitamin
Sized in line with other large-format capsules and multivitamins already swallowed daily by millions of people.
Under the hood: a 300-hour battery and Bluetooth 5.0 keep the capsule streaming data for the full Session, in production-ready hardware manufactured by our technical co-founders at DotSpace.
One Session gives you a snapshot. Repeat Sessions give you a pattern.
Voyana runs on a subscription model — $299 to start includes your first session, plus $19/month for a new session every 6 months, ongoing tracking, trend history, and monthly experiments. Like a CGM sensor, you replace the capsule to keep tracking how your gut responds over time: after diet changes, travel, stress, or simply to check in. Pricing is subject to change before launch.
