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
ONDA gives live heart-rhythm feedback and a coherence score while you breathe, using just the iPhone camera or an Apple Watch — no chest strap — inside a guided, progressive 8-level practice. It’s the most accessible way to actually train HRV, not just track it.
Pros- +Real-time HRV biofeedback + live coherence with no extra hardware
- +Works with the iPhone camera or an Apple Watch you already own
- +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 most accurate readings need a chest strap, and it’s more measurement tool than guided practice — but for raw HRV precision 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
- Best for breathing-exercise variety
A large library of guided breathing exercises. It adds HRV/coherence biofeedback only in its premium tier and via a Bluetooth heart-rate device — so biofeedback is an add-on rather than the core, but the exercise range is the widest here.
Pros- +The widest library of guided breathing exercises
- +Polished UX; calm/focus/sleep programs
Cons- −HRV biofeedback is premium-only and needs a Bluetooth device
- −Biofeedback is an add-on, not the core
THE BOTTOM LINE
For accessible, guided HRV biofeedback with no extra hardware, ONDA leads. If you want the most precise measurement and don’t mind a chest strap, choose Elite HRV. If you mainly want a big library of breathing exercises with biofeedback as an option, 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 that works with just your phone or Apple Watch, ONDA Life leads. Elite HRV is the most measurement-focused (best with a chest strap), and Breathwrk offers the widest breathing-exercise library with biofeedback in its premium tier. 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 — it uses the iPhone camera (PPG) or an Apple Watch. Elite HRV’s most accurate measurement uses a chest strap. Breathwrk’s biofeedback needs a Bluetooth heart-rate device.
