WHAT'S BIOFEEDBACK?
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

You can learn more about the psychological and physiological benefits of deep breathing and HRV Biofeedback, at HRV4Biofeedback.com

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

Good app. Could use some improvements.

I’ve really benefitted from regular RF breathing and biofeedback using this app. It’s really helped me manage stress much more effectively. I do wish there were a more robust set of external accessories.

I often want to practice hands free, so I don’t need to be holding my phone to use the app, and I’m not aware of an external device that both measures your HRV and gives a vibration and quiet sound indicating the breathing intervals.

XLT10, 18/02/2020

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.

Amazing results!

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.

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.

demihemi06089, 08/05/2020

Still beta quality

I love the amount of detailed science this developer provides on their website but this app isn't usable and it is mostly a documentation problem.
1. The lower limit on breathing rate is stupid and immediately meant the pace was too fast for me.
2. Nowhere is the circle explained.
3. It isn't biofeedback unless there is something that's feedback for me. Just following the pacer is guided meditation at most.

I hate to say it but stop trying to explain (or defend) the science and tell the user what they should do.
If you aren't certain what that means then you need to spend more on UX

No response from the developers after two weeks and there's a bug where it starts showing the pulse as being in the 30s even when it clearly isn't and there is a strong signal

DocDSO, 11/07/2020

Incredible

As a doctor of physical therapy and a biofeedback practitioner for several years using very high end and costly equipment from Thought Technologies/Montreal Canada, the functionality in this app is spot on and exceedingly advanced for the price and simplicity. Would highly recommend pairing it with the Polar strap.

Gamechanger

I bought my iPhone SE just to use these apps, and they do not disappoint. Major boost to daily insight into your health, with a reliable way to induce parasympathetic nervous system response and relax into being a healthier person.

Nicky820, 29/05/2020

Not only for elite athletes

As an active senior, I rarely miss a morning where I don’t use this App. Keeps me honest so that I don’t over train. That morning resting heart rate feature can set the tone for what kind of activity would be best for that day, as well.

Ze Stuart, 27/06/2021

A powerful meditation tool

I’ve found this tool incredible helpful for dealing with stress and fatigue.

My only improvement would be a more subtle way to notify the peak and trough of the breathing cycle.

Alexster0192, 24/02/2021

Without a separate sensor it’s useless

I got this to see if I could avoid spending the money on a more expensive device. Conclusion is I cannot; using the camera as a sensor (at least on my iPhone SE) is a fool’s errand, it shuts off after ten seconds due to inability to consistently detect. I haven’t been able to use the app at all. Waste of money for me.
