ONDA vs Oura Ring
Oura is a smart ring that passively tracks your sleep, readiness and overnight HRV. ONDA is an app that actively trains your nervous system with real-time HRV biofeedback while you breathe. They answer different questions — "how did I recover?" vs "can I shift my state right now?" — and many people use both.
VERDICT
Different jobs. Oura measures your recovery overnight; ONDA trains your state in the moment. If you want a readiness score, Oura. If you want active HRV biofeedback, ONDA. Together they cover both — track with Oura, train with ONDA.

Questions
Is ONDA a replacement for an Oura Ring?
Not exactly — they do different things. Oura passively tracks sleep, readiness and overnight HRV; ONDA is an active HRV biofeedback trainer you use during breathing practice. Many people use both: Oura for measurement, ONDA for training.
Does ONDA need a ring or wearable like Oura?
No. ONDA works with the iPhone camera (pulse/PPG) or an Apple Watch you already own — there is no dedicated wearable to buy.
