Real-time HRV metrics, live graphs, and precise RR interval tracking with your Polar sensor. A clear, calm way to understand your inner rhythm.
Hoogga is a real‑time HRV companion that helps you observe your inner rhythm, with clarity and calm.
Designed for people who want precise HRV metrics, clean visuals, and a warm, grounding experience. Connect your Polar heart rate sensor and watch your inner rhythm unfold in real time.
In a world that demands you go faster, Hoogga invites you to slow down and listen to your inner rhythm. “Hoo” is the soft sound of an exhale. “Gga” is grounding — the moment you return to yourself.
Every breath is a homecoming.
Hoogga connects with your Polar heart rate sensor to stream RR intervals and display clean, real‑time HRV metrics and graphs. It is designed for people who want precise HRV data, minimal noise, and a warm, grounding experience.
Requires a Polar heart rate sensor.
Hoogga works exclusively with Polar devices that support RR interval streaming. A compatible Polar sensor is required to start a session.
