Description

Plena Biofeedback
Plena: The Only Mindfulness App with Stress Zones, Intentions, and Readiness Scores

Start mindfulness sessions from your Apple Watch with live sensor streaming to iPhone. Set an intention before each session, see real-time stress zone classification as you practice, then reflect afterward. Track daily readiness with a score showing exactly which metrics help or hinder recovery.

What Makes Plena Different

- WATCH-FIRST: Start from Apple Watch with live data streaming to iPhone
- STRESS ZONES: See Calm/Optimal/Elevated zones update in real-time
- INTENTIONS + REFLECTIONS: Set goals before, record insights after
- READINESS BREAKDOWN: Daily score with metric contributions explained
- MIND-BREATH-BODY: Built on the triangle of HR, HRV, and respiration
- PRIVACY-FIRST: Health data stays on your device, never shared

The Triangle: Mind, Breath, Body

The triangle represents the three core rhythms of human calm:
- Heart Rate reflects moment-to-moment activity
- HRV shows adaptability and stress balance
- Breath regulates the entire system

When in harmony, they create balance. That's what Plena measures in real time.
