What the RHz setup includes
The phone provides the guided pacer, session workflow, on-device history, and export tools. The external monitor supplies the beat-to-beat timing needed for real biofeedback sessions.
- RHz Android app — free to use, no subscription or RHz account
- Compatible Bluetooth heart-rate monitor — Polar H10 recommended
- Optional headphones or haptics for pacing feedback
Where dedicated hardware may still fit
Dedicated systems can offer bundled sensors, specialized support, or workflows designed for professional environments. RHz is built for personal wellness practice and experimentation, not clinical use.
The trade-off to understand
RHz lowers the software barrier, but it does not remove the sensor requirement. You still need compatible external hardware and are responsible for setup, signal quality, safe use, and interpreting the app as a wellness tool rather than a medical device.
