MUUM: Your daily breathing ritual What is MUUM? A breathing app for daily life. Short rituals - one to fifteen minutes - that bring your breath back through the nose. Designed in Switzerland by engineers from EPFL and ETH Zürich. Why nasal breathing? Most of us breathe through the mouth without realizing it - at night, at work, on a run. The nose is built to filter, warm, and slow the breath. The mouth is not. MUUM guides you back to nasal breathing through audio sessions, real-time biofeedback, and slow breathing patterns. Three rituals, three moments Energy: short activating sessions for the morning or a midday reset. Calm: slow nasal breathing to wind down before sleep or between meetings. Focus: structured patterns before work, study, or sport. - Garmin & Apple Health integration - Live biofeedback (Heart Rate Variability, Heart Rate) - Guided sessions from 1 to 15 minutes - Real-time breath tracking with visual feedback - Coherence breathing at 6 breaths per minute - New rituals added every month - Progress tracking A physical and digital ritual MUUM also makes scented nasal breathing strips, sold in pharmacies across Switzerland and France. The app works on its own, or alongside the strips for a full sensory experience with subtle scents - lavender, sandalwood, or fragrance-free. Also used by athletes MUUM is used by ATP tennis players, World Tour cyclists, and ultra-trail runners preparing for major events. Our nasal strips product line has shipped over 200,000 units. Designed in Switzerland MUUM is a Swiss breathing brand, founded in 2024 in Nyon. Our products are built by engineers from EPFL and ETH Zürich.
