Aerio: Guided Breathing

Most breathing apps give you a timer and a circle. Aerio adds what actually tells you it's working: real heart-rate feedback on your Apple Watch, and no gimmicks. GUIDED BREATHING, DONE RIGHT 18 techniques — Box breathing, 4-7-8, Coherent breathing, Physiological Sigh and more — each with exact timing. Follow the circle, feel the haptic cue at every phase change. BUILT FOR A REASON, NOT A MOOD Presets grouped by purpose: Sleep, Focus, Stress relief, Energy. Pick what you need, not what looks nice. APPLE WATCH, FULLY INTEGRATED A standalone Watch app with its own session flow — no phone required nearby. MINDFUL MINUTES, AUTOMATICALLY Every session logs to Apple Health as Mindful Minutes. PROGRAMS AND COLLECTIONS Multi-day programs guide you step by step. Curated collections bundle the right technique for the moment. YOUR PROGRESS, AT A GLANCE Streak, weekly overview and a calm score derived from your heart-rate trend. CALM DESIGN, NO WELLNESS CLICHÉS No forced positivity, no unrealistic claims. Just a clear, distraction-free breathing session. Aerio is a practice app, not a medical product, and offers no advice or treatment.
