Finally measure what's happening inside.
Voyana is the first ingestible biosensor for digestion — a swallowable capsule that captures pH, motility, temperature, and pressure across your GI tract during a simple multi-day session. No guesswork, no food diaries. Real data behind every choice you make about your gut.
Pre-launch. No spam — just milestone updates as we head toward FDA clearance.
Digestion is a black box.
60–70 million Americans live with daily GI symptoms — bloating, IBS, food sensitivities, reflux — and have no real way to know what's actually happening inside.
No way to measure
Bloating, IBS, and food triggers go undiagnosed for years. There's no everyday way to see what's really going on.
Clinical-only options
Endoscopy and colonoscopy exist, but they're invasive, costly, and reserved for when symptoms are already serious.
Guesswork everywhere
Elimination diets and food journals are the default tools today — and they miss what the gut is actually doing.
Every other vital sign has a wearable. Digestion is next.
Voyana meets you where your gut is.
Bloating
The same meal can land differently from one day to the next. See what's actually happening, not just how it feels.
Irregularity
Motility that speeds up some weeks and stalls others. Voyana tracks the pattern instead of one data point.
Food triggers
Personalized trigger maps show which foods drive symptoms for you — not a generic elimination list.
Energy & digestion
See how digestion shows up in the rest of your day — energy, sleep, and recovery, woven into one score.
Measure. Track. Understand.
What CGMs did for glucose, Voyana does for digestion.
Measure
An ingestible capsule senses pH, motility, and transit — the same biomarkers used in clinical research — as it travels your GI tract.
Track
Log meals in the Voyana app while the capsule streams data continuously across a 2-4 day session.
Understand
Patterns emerge — which meals settle, which don't, which times matter. Your Gut Score, Trigger Map, and next steps.
Confusion to clarity in about four days. See the full mechanics →
The complete picture, from inside your gut.
Gut Score
A daily 0–100 measure of how your digestion is doing, built from data captured inside your GI tract.
Trigger Map
Foods, meals, and times of day correlated with reactions — personalized to you, not a generic elimination list.
Actions
Personalized swaps and experiments: what to try next, based on how your own gut actually responded.
pH & Motility
Direct luminal measurement of acidity and transit speed across the stomach, small intestine, and colon.
Pressure & Temperature
Signals tied to contractions and inflammation, captured continuously as the capsule travels.
Sessions + Refill
Four sessions annually for around $299, plus a low-cost monthly subscription to keep tracking how your gut changes over time.
We track sleep, heart rate, glucose, movement, and stress in real time — but digestion remains a black box. Voyana is changing that.
Ingestible sensors aren't new. They're just new to gut health.
The category has been FDA-cleared and safely used across clinical, consumer, military, and athletic settings for nearly four decades.
Ingestible thermometer (NASA / Johns Hopkins). Adopted by the NFL and US military.
Capsule endoscopy (Given Imaging). Class II FDA clearance.
Wireless GI motility capsule (Medtronic). FDA-cleared.
Consumer vibrating capsule for chronic constipation. FDA-authorized.
Gas-sensing biomarker capsule (Atmo Biosciences). 510(k) cleared.
First-in-human results published, peer-reviewed in WJES, Stanford-co-led.
First-in-human. Peer-reviewed.
The capsule platform behind Voyana is already validated in a published clinical trial, co-led by Stanford's Department of Surgery.
Three bets on how to measure digestion. Only one measures from inside.
| Voyana | Suna | Throne | |
|---|---|---|---|
| Form factor | Ingestible capsule (12mm) | Abdominal patch (external) | Toilet-mounted device |
| Sensing modality | Direct luminal sensing inside the GI tract | Acoustic — gut sounds through skin | Computer vision — analyzes bowl contents |
| Biomarkers | pH, pressure, temperature, motility | Gut sound patterns only | Stool morphology, hydration, frequency |
| Sensing depth | Endoluminal (medical-grade) | Trans-abdominal (indirect) | Post-transit (after the fact) |
| Clinical validation | Peer-reviewed first-in-human trial (WJES, 2025) | No published clinical trial identified | No published clinical trial identified |

Three things had to happen first.
The technology is ready
Lab-grade ingestible pH and motility sensing now works outside a hospital. What used to require clinical equipment fits inside a swallowable capsule.
Demand is exploding
Searches for "gut health," "bloating," and "food sensitivity" are at all-time highs. Digestion is the fastest-growing health concern among US adults under 40.
Biosensors are normal
Oura, Whoop, and CGMs like Levels, Lingo, and Stelo trained millions of people to trust — and pay for — biosensor data.

You already trust this kind of data.
Each of these brands taught people to wear, or swallow, a sensor every day and trust what it tells them. Voyana brings that same kind of daily, data-backed insight to digestion.
Not just a wellness trend.
The science, the evidence, the boundaries.
Not yet. Voyana is pre-launch, targeting a Q1 2027 release pending FDA 510(k) clearance. Join the waitlist to get milestone updates as we get closer.
Voyana is actively pursuing an FDA 510(k) pathway, targeting roughly a 12-month timeline. Until cleared, Voyana is offered as general wellness information, not a diagnostic or medical device. Always consult a qualified healthcare professional about any health concern.
Ingestible sensors are a well-established category — FDA-cleared since CorTemp in 1988, with more than 5 million devices used safely to date, a pooled retention rate under 1%, and no reported aspiration events in roughly 30 years of clinical use. The Voyana capsule passes naturally; no retrieval is required.
A microbiome test is a single frozen snapshot that takes weeks to come back. A CGM measures glucose in tissue, not digestion. Voyana measures pH, motility, temperature, and pressure directly inside the GI tract, continuously, over a multi-day session — see the full comparison.
Getting started is a one-time $299 — welcome kit, app activation, and your first session included. Ongoing access is $19/month, which includes four capsule sessions every year, continuous tracking, and trend history. Additional sessions are available at $99 each. Active membership is required to redeem included sessions. Pricing reflects current planning and is subject to change before launch.
Our vision: the default way to understand how food becomes you — a personalized nutrition operating system, starting with the gut.
