Cohera vs Weight

Use your mind to align your heart. Cohera is a mind-driven heart-coherence trainer for Apple Watch. Bring your attention into the moment, pick a target rhythm, close your eyes, and guide your heart into sync while a living visualization drifts on screen. The whole point is that you can stop staring at numbers — the guidance is something you feel, not something you watch. When you're done, you get one honest score and a real sense of having slowed down. HOW IT WORKS Soft lub-dub haptic pulses pace your breath through your wrist — the gentle mechanism that helps your mind settle your heart into rhythm, tightly synced to the on-screen visual. Run a whole session with your eyes shut — no screen to stare at. ONE HONEST SCORE The Coherence Index (0 to 100) shows how closely your heart settled into your chosen rhythm, in plain language — Dispersed, Balanced, Aligned, Harmonic — instead of a wall of stats. FOUR RHYTHMS, ONE APP Choose your pace: Deep Rest, Calm Flow, Active Focus, or Walk & Talk. The same app helps you wind down and stay composed while you move. FOUR AMBIENT VISUALS Breathing Orb, drifting Particles, Fire, and Horizon Breath. Color and motion shift with your coherence — a living visual, not a chart. NUMBERS STAY OUT OF YOUR WAY The clock is hidden during a session and your data graph waits for the post-session summary. Coherence first, by design. PRIVATE BY DESIGN Cohera runs on the Apple Watch you already own and works with your own heart-rate data. No account required to start. HONEST ABOUT WHAT IT IS The Coherence Index is Cohera's own measure of how well your heart followed your target rhythm — it's a training signal, not a medical or diagnostic tool. Cohera is for everyday calm and focus; it doesn't treat, diagnose, or prevent any condition. Built by an independent developer who wanted a calm session you can do with your eyes closed — and proof it actually worked.
