Did you know that your heart beats faster during inhalation and slower during exhalation AND did you know that this is good for you? The technical term is RSA (respiratory sinus arrhythmia) - a good arrhythmia controlled by your autonomic nervous system. High variability of the heart rate stands for a good autonomic balance and activity of the parasympathetic nervous system (rest and relaxation nerve). HeartBreath is a biofeedback tool, that addresses exactly this relationship between breathing and heart rate. The app guides you through a simple slow-breathing exercise (with pictures and sounds), while detecting and displaying the intervals between your heartbeats. You can measure, train and evaluate your personal status. No additional hardware devices are needed. HeartBreath is able to detect heartbeats by positioning your finger on the lens of the phone’s camera. KEY FEATURES: Integrated VaYou Sound Flows, which provide an exceptional sound experience on acoustic pacing. High quality and customizable control of the bio-feedback exercise with pictures (you can work with pictures from your photo library) and sounds. Live display of the current heart rate and variability values while recording. In just a few breaths, HeartBreath is able to compute your resting heart rate. No additional hardware is needed. The calculation works with a finger on the lens of the iPhone’s (or iPod’s) camera (for iPad only device models with flash). Optionally, an external heart rate monitor can be used. For compatible devices (Polar H10) display/recording/evaluation of true ECG data is supported. As a special extra, the app allows the comparison of data between the finger on the camera and the heart rate monitor. Unlike many other HRV apps, HeartBreath offers a precise visualization for every single heartbeat and, if necessary, tools for interactive correction of the beats. This is very important for the high reliability of HRV parameters, since single ectopic heartbeats or data artifacts can result in strange adulteration of HRV values. Integrated tools to determine your optimal breathing speed. Various studies show that each person has an individual optimal RSA breathing rate in the range between 4 and 7 breaths per minute. Trend evaluations over longer periods of time. HeartBreath integrates with the Apple Health app. Privacy is important to us! The app does not require registration and you have full control over the data of your sessions, which is only stored on your phone. ## Key features - Guided slow breathing exercises - Heart rate variability measurement via camera - Customizable visual and auditory biofeedback - Live heart rate and variability display - Optimal breathing speed determination - Long-term trend evaluations - Apple Health integration ## Pricing and in-app purchases Base price: $8.99. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | ECG Pro Features | $8.99 | one-time | | Eternity VaYou Sound | $3.99 | one-time | | Wind & Waves VaYou Sound | $3.99 | one-time | | Burma Bliss VaYou Sound | $3.99 | one-time | ## Recent user reviews (10 of 22) All indexed reviews: https://appshunter.io/ios/app/heartbreath-hrv/id1380171851/reviews.md ### 5/5 — Best biofeedback app on iOS *2026-03-15* This app may seem unrefined at first glance, but it well and truly makes up for it in simplicity, functionality, and not trying to be a wholistic wellbeing app. There’s no unsolicited “wellbeing guidance” that leaves you feeling more stressed, It does one thing, and it does it perfectly. Well worth the money and the internal upgrades. I use it 3x a day for 5+ minutes each session, with a polar H10 when at home, and the camera when out and about. It’s helping me re-condition my autonomic nervous system after two decades of deconditioning and dysautonomia. The only things that would make it better for me are: - Apple Watch ECG as an input - An optional HRV/time plot view - Auto breathing rate optimisation ### 1/5 — Nutzlos *2025-06-23* Ich verwende mehrere Atem Apps und teste immer wieder mal neue. Das mit dem Finger auf die Kamera legen ist für mich sinnlos, weil man die Hand in einem unnatürlichen Winkel hält, immer aufs Display schauen muss und somit ich entspannen kann. Apps mit Biofeedback sind deutlich effektiver. Bei dieser App hier bin ich mehr gestresst als das es hilft. Da gibt es besser Apps. ### 4/5 — Was da los mit Apple Watch? *2025-02-03* Eigentlich ganz gut, aber ich frage mich, warum es keine Apple Watch integration gibt? ### 5/5 — Super *2025-01-27* Schade, dass es nicht mit der Apple Watch funktioniert. Sonst 10/10 ### 5/5 — Apple Watch *2024-11-29* Die App ist wirklich sehr genial und ich würde mir von ganzem Herzen wünschen, dass sie auch auf der Apple Watch funktioniert, damit man kein zusätzliches Tool benötigt, um die HRV zu messen. ### 1/5 — Waste of money *2024-04-14* This is the worst app I’ve ever spent money on. It consistently tells me I have a poor connection for both the finger on the camera and my Polar H10. ### 5/5 — Super App!! *2023-01-01* Unglaublich gut gemacht. Großes Lob an die Entwickler! 👍 Die Sounds für den Breath-Pacer sind einzigartig, man kann sich ganz fallen lassen und wird nicht wie in anderen Apps ruckartig zum ein- oder ausatmen erinnert - es fliesst intuitiv und man kann super damit üben. **Developer response:** Herzlichen Dank für diese sehr motivierende Bewertung! ### 1/5 — Soldi buttati *2022-05-29, version 3.2.1* Non funziona con la fotocamera, quindi è totalmente inutilizzabile. Soldi buttati ### 5/5 — 5 glanzvolle Sterne *2022-04-30* Hallo HeartBreath Team, ich nutze Eure App nun seit Ende Januar und bin dankbar, Euch entdeckt zu haben. Mit bis zu 100 Extrasystolen pro Tag vor ca. 6 Monaten und mehr oder weniger ergebnislosen Untersuchungen bei Kardiologen fand ich einen auf Psychosomatik spezialisierten Arzt mit Fokus auf „Herzpatienten“, der mir das atemgesteuerte HRV Training näher brachte. Und so begann ich 1x pro Woche in seiner Praxis mit einer medizinischen HRV Trainingslösung zu trainieren. Kurz nach meinem ersten Training war ich auf der Suche nach einer Möglichkeit, das Training täglich zuhause durchzuführen und bin schließlich auf Eure App gestoßen. In Kombination mit dem Polar H10 Brustgurt finde ich Eure Lösung klasse! Und mache nun nach 100 Traingssessions (🏆) langsam Fortschritte = der HRV Wert verbessert sich während der Messung auf rin durchschnittlich immer höheres Niveau. Und das freut mich und gibt mir etwas Hoffnung, dass ich mein hohes Level an Stress (das zeigen 24h HRV Stressmessungen, u.a. mit MyAutonomHealh) vielleicht doch in eine positive Richtung verändern kann. Danke für Eure Ideen und Entwicklungsleistung, die Ihr in diese App gesteckt habt 🙏🏻 5 glanzvolle Sterne ⭐️⭐️⭐️⭐️⭐️ **Developer response:** Hallo "weisser_riese": Wir freuen uns über jede Art von Rückmeldung, aber natürlich besonders, wenn ein Anwender zufrieden ist und mit Hilfe der App auch positive Effekte erkennen und erreichen kann - vielen Dank für dieses sehr motivierende Feedback! ### 5/5 — Ottima applicazione *2022-03-24, version 3.1.2* Complimenti ## Frequently asked questions about HeartBreath HRV ### What does HeartBreath HRV do?
