## What is Hoogga?

Hoogga is a real‑time HRV companion designed to help you understand your inner rhythm with clarity and calm.  

Hoogga offers three tools to help you observe, regulate, and understand your internal state:

Real‑Time HRV 
See your HRV shift moment by moment
- RMSSD, SDNN, LF/HF, and more
- Live HRV graph
- Clean, minimal visuals
- Export HRV metrics and graphs


Biofeedback Breathing 
A guided breathing space for calm and regulation (usable with or without Polar)
- 10 breathing tempos
- 3 session durations
- Visual breathing guide
- 3 audio modes
With Polar connected, you’ll also see:
- HR Waveform
- RSA Amplitude
Observe how your breath influences your physiology in real time.


Resonant Frequency Assessment 
Find the breathing pace that calms your body best. Requires a Polar sensor to analyze real‑time HRV and RSA.
- Choose from 10 tempos
- Compare responses
- Discover your personal resonance frequency

Data Export  
Whenever Polar is connected, Hoogga records a complete RR intervals session. Each session is labeled with tool, date, and time for exports.


Hoogga is designed for people who want precise HRV data, clean visuals, and a warm, grounding experience — without pressure or noise.
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.
Use it during rest, after stress, before sleep, or anytime you want to reconnect with your body.
