Master your breath and meet your better self.

The ability to control your stress, sharpen your focus, and improve your health isn’t a superpower. It’s a skill. And now, Tummo teaches you how to master it with ease.

Turn Your Breath Into Your Most Powerful Tool.

Mastering your inner state doesn’t require years of practice or intense concentration. It requires the right guide. Tummo makes the process simple, intuitive, and automatic.

See Your Inner World

The lightweight Tummo sensor reveals your real-time breath quality, translating the invisible patterns of your nervous system into simple, understandable data on your phone.

Receive Gentle Guidance

You don’t have to think. When Tummo detects shallow stress breathing, a gentle, silent vibration cues your body, guiding you back to a state of optimal performance and calm.

Achieve Lasting Change

With consistent use, Tummo trains your body to prefer deep, diaphragmatic breathing. This new habit becomes your automatic response to stress, improving your baseline resilience.

The Difference Between Guessing and Knowing.

Health apps can remind you to breathe, but they have a fatal flaw: they can’t see if you’re doing it right. By focusing on the one muscle that matters—the diaphragm—Tummo provides a level of precision that makes true change possible.

Bio-feedback, Perfected

Tummo closes the loop between mind and body. You feel the vibration, you adjust your breath, and you see the immediate result in your tummo app. This is how your brain learns new, better habits.

Harnessing the Vagus Nerve

Deep, diaphragmatic breathing is your body’s most direct way to activate the vagus nerve, which tells your brain and body to switch out of “fight-or-flight” and into a state of “rest and digest,” lowering stress hormones instantly.

One Skill. Infinite Impact.

The skill of better breathing compounds over time, enhancing every area of your life.

Build Resilience to Stress

Master your body’s response to daily pressures. Tummo acts as an early warning system for stress, guiding you back to a state of calm before anxiety takes hold, making you less reactive and more composed.

Sharpen Focus & Performance

Optimal breathing increases oxygen supply to your brain and muscles. For athletes, this means more endurance. For professionals, it means sharper focus, better decision-making, and sustained concentration during deep work.

Improve Sleep Quality

Train your body to maintain a calm, steady breathing pattern throughout the day. This helps you fall asleep faster, reduces nighttime disturbances, and increases the time spent in deep, restorative sleep stages.

Accelerate Recovery

For those recovering from surgery or managing chronic conditions like asthma, proper breathing is non-negotiable. Tummo ensures prescribed breathing exercises are performed correctly, accelerating healing and improving outcomes.
