Effortless Stress Relief.
Tummo retrains your breathing so your body naturally returns to calm.
- SCIENCE-BACKED
- REAL-TIME RESPONSE
- WORN ALL DAY
THE PROBLEM
Anxiety starts in your body before it reaches your mind.
Stress changes your breathing first – shifting you into shallow, fast breathing before you’re aware anything is wrong. By the time you notice, you’re already spiraling.
— EVERY OTHER SOLUTION
- Requires you to notice stress first
- Relies on discipline, reminders, and routines
- Shows you data after the moment has passed
- Adds more to your mental load
- Meditation apps you open — and forget to open
— TUMMO
- Detects stress before you notice it
- Works automatically, no effort required
- Intervenes in real-time, in the moment
- Retrains your breathing over time
- Calm becomes your default, not your goal
HOW IT WORKS
Detect. Guide. Retrain.
Detects
Tummo’s ultra-slim sensor monitors diaphragm movement, recognizing the earliest signals of stress — shallow, rapid breathing — before you notice anything is wrong.
Responds
Retrains
With repeated guidance, your body learns a new default. After 90 days, most users breathe deeper automatically — even in moments that used to trigger anxiety.
Change your breath. Change everything.
Less anxiety
Stay calmer in meetings and stressful conversations.
Sharper focus
Feel in control
Better sleep
Calmer breathing helps your body unwind.
Your nervous system, finally under control. Calmer in meetings. Clearer in thought. Asleep when your head hits the pillow.
Deeper breathing, made automatic.

OUR STORY
Built by someone who needed this to exist.
Tummo started with a simple frustration: every stress-management tool required you to already be calm enough to use it. Meditation apps, breathing reminders, wearable dashboards — they all demand the one thing you don’t have when you’re anxious: presence of mind.
We spent two years asking a different question: what if the device could do the work for you? What if your body could be quietly guided back to calm before the spiral started?
Tummo is our answer. Backed by the latest research in respiratory neuroscience and built for real life.
— The Tummo Team
“Tummo is a quiet nudge toward confidence – a gentle vibration that reminds you to breathe deeply when you need it most, so you feel better, faster.”
— Michael Brunet | Tummo’s Founder
THE SCIENCE
Deep breathing improves mental health
When breathing slows, your body relaxes. Tummo helps that happen automatically.
Your Nervous System Can Relearn Calm
Slow breathing activates the body’s natural “rest and digest” response — improving emotional stability over time.
Lower Cortisol. Lower Anxiety.
Deep breathing has been shown to reduce cortisol and measurable stress markers linked to chronic anxiety.
Works Faster Than Meditation
Structured breathing improved mood and reduced anxiety more than mindfulness meditation in clinical studies.
