Kiri: Breathwork & Breath Hold

Reset stress in as little as a minute.

A calm, modern breath-training app. Follow gentle guided breathing, train with breath holds and build a simple daily habit that helps you feel calmer and more focused.

BREATHE YOUR WAY TO CALM
• Clear inhale, hold and exhale cues with soft sounds and haptics
• 10+ guided methods: Box Breathing, 4-7-8, Diaphragmatic, Coherent, Nadi Shodhana, Bhastrika, Ujjayi, Pursed Lip and more
• A minimal breath hold timer and a Breath Test to find your longest hold
• Quick Reset: one tap for about a minute of gentle breathing, from Home, Control Center, the Action Button or Siri
• Sleep mode: a timed wind-down that dims the screen, silences the haptics and fades the sound out on its own (longer timers with Premium)
• Start free with Basic Hold

TRAIN YOUR BREATH HOLD
• Breath Test history: every test is saved, with a progress chart and a weekly retest reminder
• CO₂ and O₂ tables built from your best hold, from Gentle to Challenging (Premium, your first table is free)
