Calm is a skill. Aeris teaches it, one breath at a time. Most calm apps hand you a library and wish you luck. Aeris asks how you feel, then picks the breathing protocol that matches — and stays with you through it, out loud, in your language. TONIGHT Your shoulders drop, your breath slows, and sleep arrives more easily. IN A FEW WEEKS You recover faster after hard moments and stay steady for longer. OVER MONTHS Calm becomes something you can call on whenever you want it. — 27 BREATHING PROTOCOLS — Physiological sigh, box breathing, 4-7-8, resonance, alternate nostril, Buteyko, Kapalabhati, cooling breath and more. Each one carries its real timing, its evidence level, and a plain description of what it is for. Adjustable tempo where the technique allows it. — 35 GUIDED MEDITATIONS — Body scan, breath counting, loving-kindness, noting, open awareness, gratitude, sleep wind-down. Every cue is spoken, not just written. — VOICE GUIDANCE IN 11 LANGUAGES — The guide tells you the route and the count: "in through the nose, four seconds." You can practise with your eyes closed. English, Turkish, French, German, Spanish, Portuguese, Italian, Russian, Japanese, Korean and Arabic. — 53 SOUNDS YOU LAYER YOURSELF — Rain, ocean, forest, fire, wind, night insects, room tone, white and brown noise. Mix up to four at once with per-layer volume, and let them breathe with you. — A FIELD THAT MOVES WITH YOUR BREATH — Every session draws a living Metal-rendered field, seeded by the practice and the moment. No two sessions look the same. — PROGRESS THAT MEANS SOMETHING — Coherence minutes, mood before and after, a twelve-week mark season, streaks that forgive. — ALSO — Home Screen widgets and Lock Screen Live Activities. Apple Watch companion, which writes finished sessions to Apple Health as mindful minutes.
