Best HRV Biofeedback Apps
HRV biofeedback means seeing your heart-rate variability in real time and adjusting your breathing to train it — not just recording it overnight. Only a handful of apps actually do this. Here are the ones that do, ranked, with honest pros and cons and who each is really for.

- Best overall for accessible, guided biofeedback
With an Apple Watch, ONDA gives live heart-rhythm feedback and a live coherence score while you breathe — no chest strap — inside a guided, progressive 8-level practice. Without a watch, the iPhone camera gives a pulse and breathing-rate check to start. It’s the most accessible way to actually train HRV, not just track it.
Pros- +Real-time HRV biofeedback + live coherence with an Apple Watch — no chest strap
- +Start with the iPhone camera; baseline from Apple Health (Apple Watch or another tracker that syncs there)
- +Guided, progressive 8-level path; free to start
Cons- −iOS only today (Android is a waitlist)
- −Not a passive all-day tracker or a big meditation library
- Best for measurement precision
A serious, data-first HRV app with a live coherence breathing pacer and morning readiness. Its cleanest readings come from a paired ECG chest strap, at rest, and it’s more measurement tool than guided practice — but for raw HRV numbers it’s excellent.
Pros- +Most measurement-focused; chest-strap accuracy
- +Resonance breathing pacer with live HRV
- +Free core app
Cons- −Best accuracy needs a chest strap
- −More data tool than guided practice
- Breathing exercises without biofeedback (for contrast)
A library of guided breathing exercises, classes and programs (now part of Peloton). Its official materials describe no heart-rate or HRV feedback (checked 2026-10-11), so it is not a biofeedback app — included here because many people compare it with one. Choose it for guided technique, not for training against your HRV.
Pros- +50+ guided exercises (100+ on Pro), daily classes and programs
- +Free tier; iOS, Android and web
Cons- −No documented heart-rate or HRV feedback
- −You breathe along without seeing your heart respond
THE BOTTOM LINE
For accessible, guided HRV biofeedback with an Apple Watch and no chest strap, ONDA leads. If you want the cleanest readings from a paired ECG chest strap at rest, choose Elite HRV. If you mainly want guided breathing exercises and classes without biofeedback, choose Breathwrk. For passive overnight HRV tracking (not biofeedback), a ring or band like Oura or WHOOP is a different tool entirely.
Questions
What is the best HRV biofeedback app?
For accessible, guided real-time HRV biofeedback with an Apple Watch and no chest strap, ONDA Life leads. Elite HRV is the most measurement-focused (best with a chest strap), and Breathwrk is a guided breathing-exercise app without documented HRV feedback. The best one depends on whether you want a guided practice or the most precise measurement.
What’s the difference between HRV biofeedback and HRV tracking?
HRV tracking passively records your HRV (often overnight) so you can see trends — what rings and bands do. HRV biofeedback is active: you get live feedback while you breathe and train your heart rhythm in the moment. This list is about biofeedback apps, not passive trackers.
Do I need a chest strap for HRV biofeedback?
Not with ONDA — live biofeedback uses an Apple Watch, and the iPhone camera (PPG) gives a quick check without one. Elite HRV gets its cleanest readings from a paired ECG chest strap, at rest. Breathwrk does not describe any heart-rate measurement.
