## Description

Breathe, and your heart follows. Kohaer measures your heart coherence in real time with your Bluetooth chest strap and guides you to calm. 100% private.

 Find calm, one breath at a time.

 Kohaer turns your heart rhythm into a guide toward serenity. With heart coherence — a proven breathing technique — you ease your nervous system in just a few minutes a day.

 Connect your Bluetooth heart rate sensor (Polar H10 and compatible straps), follow the breathing circle, and watch your coherence settle in real time.

 Inside Kohaer:

 • Visual breathing guide — a circle that expands and contracts at the pace you choose (4, 5, 6 or 7 breaths per minute), with an optional sound cue.

 • Real-time coherence — your coherence score and heart rate are shown during the session, measured from your actual heartbeat.

 • Sessions your way — 3, 5, 10 minutes, or a custom duration.

 • Clear summary — average score, time spent in coherence, and the session curve.

 • History — track your progress day after day.

 Privacy by design.

 Kohaer runs entirely on your iPhone. No data is collected, no account, nothing sent to the cloud. Your sessions stay with you.

 Please note: Kohaer requires a Bluetooth heart rate sensor (a chest strap such as the Polar H10). The app does not measure heart rate from the iPhone alone.

 A few minutes of mindful breathing are enough to change your day. Start now.
