01
Wear Ventos
Snap it onto your underwear and get on with your day. Ventos records hydrogen quietly, including while you sleep.
Snap it on, and you’ll forget you’re wearing it.
It records your gas day and night, lines it up with your meals and how you feel, and shows you patterns you can act on.
In the box: Ventos, a magnetic charging cable and accessories. The app works on iOS and Android.

Log Meals
A photo of what you eat. A quick daily check-in on how you feel. A little everyday context to go with your measurements.

Connect the dots
See your hydrogen alongside your meals and how you felt. Look for patterns over time, then choose what you’d like to explore.
Connect the dots
Your day, with a little more context.
Your meals. Your recorded hydrogen. How you felt. See them together, so you have something more concrete to explore.
A little context goes a long way.
Meal photos help you remember what you ate when you look back at your measurements.
A starting point, not proof of a cause. A meal and a hydrogen rise appearing on the same timeline do not establish a connection.

Your microbes don’t clock out.
Neither does Ventos. Wear it while you sleep, then give it a quick charge in the morning.

What Ventos measures
From your plate to your phone.
Your microbes make hydrogen as they break down food. Ventos measures the hydrogen that leaves as gas, giving you a continuous record to explore.
-
01
You eat.
Fiber and other foods your body doesn’t fully digest reach your large intestine.
-
02
Microbes get to work.
Your gut microbes ferment that food. Some produce hydrogen as they go.
-
03
Hydrogen leaves as gas.
Some of that hydrogen leaves your body in your farts, day and night.
-
04
Ventos records it.
See your hydrogen measurements alongside meal photos and daily check-ins in the app.

Good to know
The practical questions.
Will I feel it?
Ventos is coin-sized and snaps onto any underwear. 95% of respondents in the Human Flatus Atlas said Ventos was comfortable to wear. With no screen and no sound, most of the time you can forget it’s there.
Preliminary Human Flatus Atlas findings. Not yet published.
How do I charge it?
Connect the magnetic charging cable. Ventos charges in a few minutes, then it’s ready to snap back on.
How long do I wear it?
Wear it for a day, a week, or make it part of your daily routine.
Do I have to wear Ventos every day?
No. You can wear it every day or take breaks whenever you like. More days of wear can help you build a fuller picture of your patterns. For the Tiny Health study, we hope you’ll wear Ventos for 3 to 14 days.
What if I miss a day?
That’s okay. You can miss a day or take a day off anytime. Just pick up again when you’re ready. The big picture matters more than a perfect streak.
What does it measure?
Hydrogen in your farts, which your gut microbes make as they break down food. It doesn’t measure odor.
What if I forget to photograph a meal?
That’s okay. You can add your food later or pick up with your next meal. The big picture matters more than a perfect log.
Which phones does the app work with?
iOS and Android.
