What breathing patterns does Respirix include?

Respirix includes four research-backed protocols: Resonance (4.5s in, 5.5s out), Extended Exhale (4s in, 6s out), Slow Diaphragmatic (4-2-5-2), and HRV Biofeedback (4-2-6-2). You can also create custom patterns.

Do I need a heart rate monitor to use Respirix?

No. Respirix works perfectly as a standalone breathing exercise app with voice cues and a visual pacer. Heart rate monitoring and HRV biofeedback are optional features for users who want deeper insight.

Does Respirix work in the background?

Yes. Voice cues and haptic feedback continue when the screen is off or when you switch to another app. You can lock your phone and just listen.

Does Respirix collect my data?

No. All data stays on your device. Respirix has no accounts, no analytics, no tracking, and no ads. It works completely offline.

Just breathe.
The app does the rest.

Respirix is a simple, focused breathing app. Pick a pattern, tap start, and follow the voice cues. No complexity, no learning curve — just better breathing in seconds.
