Breathe. Reclaim your calm.

Free · In‑App Purchases

Breathe better. Stress less. Measure the difference. iKima is a science-backed breathing trainer for iPhone and Apple Watch. Every session is guided on your wrist and measured in your heart — so you can see calm happening, not just feel it. YOUR WATCH. YOUR COACH. Start a session on Apple Watch and follow the breathing ring. iKima tracks your heart rate live, so every inhale and exhale is backed by real biofeedback — not just a timer. 5 TECHNIQUES FOR EVERY MOMENT • Physiological Sigh — a double inhale and long exhale: 60-second emergency calm • Box Breathing (4-3-3-3) — rapid focus and stress relief, anytime • 4-7-8 Breathing — wind down before sleep and activate the parasympathetic system • Belly Breathing — slow, deep diaphragmatic breaths to lower resting heart rate over time • Resonance Breathing — a 5-5 rhythm (about 6 breaths/min) to maximise HRV REAL NUMBERS. REAL RESULTS. After each session, your iPhone shows exactly what happened — average heart-rate drop, HRV (SDNN), and a full session log. Watch your vagal tone strengthen over time. TRACK YOUR NERVOUS SYSTEM HEALTH iKima shows your Sleep HRV (SDNN) — measured by Apple Watch overnight — right on your home screen. Higher numbers mean stronger recovery; consistent practice helps move you from "needs relax" (under 30 ms) toward balanced (50 ms and up). EVERYTHING SYNCS, EFFORTLESSLY iPhone and Apple Watch work together automatically. Your history, heart-rate trends, and HRV are always in one place. PRIVATE BY DESIGN No account, no data sold. HealthKit is read-only — iKima never writes to your health record, and your data stays on your device. iKima is for anyone who wants to feel calmer, sleep better, and take measurable control of their stress response — one breath at a time.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Steadier readings and a smoother start. Heart rate and HRV now stay in sync after you grant or revoke Health access, your dashboard refreshes the moment you return to it, and the welcome screen fits smaller iPhones properly.
