ONDA vs Breathwrk
Breathwrk is a large library of guided breathing exercises for calm, focus and sleep; its premium tier can add HRV/coherence monitoring via a Bluetooth device. ONDA is HRV-biofeedback-first: live heart-rhythm feedback and a coherence score using the iPhone camera or Apple Watch, no extra device. Both are breath-centred; they differ in whether the biometric loop is core or an add-on.
VERDICT
Breathwrk is breathing-first with HRV as a premium add-on; ONDA is HRV-biofeedback-first with breathing as the vehicle. For exercise variety, Breathwrk. For a built-in, device-free biofeedback loop, ONDA.
