Heart Rate Variability (HRV) Biofeedback is a technique that can directly affect physiological and psychological factors through deep breathing exercises and is an ideal strategy to help us self-regulate and better cope with stressful situations
Practically speaking, HRV Biofeedback consists of providing an individual with real-time feedback on instantaneous heart rate and respiration changes while being instructed to breathe at low frequencies

HOW CAN I BENEFIT FROM BIOFEEDBACK?
Life can be demanding, from both a physical and psychological point of view
Our health and performance can be affected by how we are able to effectively cope with stressful situations and deal with anxiety, or in broader terms, our ability to emotionally self-regulate is key
The goal of HRV Biofeedback is to improve self-regulation, therefore impacting positively our health and performance

Ratings and Reviews
Great for what it does, want it to do more
I doubted their claim of HRV and HR accuracy. I have a Polar h10 and I compared measurements and to my surprise HRV4BIOFEEDBACK optical sensor accuracy was the same as Polar! Very impressive.
I like how you get the scores and can see the effects on mood and whatnot. Helpful to see trends over time.
Major criticism is that the breathing visual is hard to see. They need to do something with more contrast.
Only rated 4 stars because there is so much more they could do with the biofeedback exercise rather than just breathing. Guided meditation, sound, etc.
Useful but can improve
Loved hrv4training so tried this also and because the developers are expert in this field. App uses a dark to light screen change that you follow to pace breathing. The dark/light lighting is not markedly different and difficult to follow. Would suggest greater dark/light difference or a bold white line or circle like “ibreathe”. Would also be very useful to have a sound or chime cue so one could close eyes during the practice and still maintain breathing pace. It would be useful to see the HRV numbers that underly the buofeedback score. I think app will become more useful with subsequent iterations and updates.
Developer Response ,
Thank you for your feedback and continued support, really appreciate it. Just a quick suggestion in terms of using the app with eyes closed, you can do so by enabling the vibration, from Menu / Settings. Take care!
This is the single most impactful app I’ve found for getting myself to center and feeling more in the “flow” state in a super short time. Replacing/supplementing my normal meditation time and the impact is amazing. There are a couple of small things I’d change on the app, but the team that makes it is awesome so I’m sure they’ll nail this; I have been using their other app (HRV4Training)and it launches new features and great updates all the time so I’m looking forward to where they go with this.
