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.

This is ONDA Life’s own guide, and ONDA is one of the apps in it — so we rank it #1 only where it genuinely leads, name where each competitor wins, and say plainly below what ONDA is not best at.
  1. #1ONDA LifeOur app
    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
  2. 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
  3. 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.
