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

Community Voice & Feedback
the heart rate isn't recorded accurately. it dropped from 80 to 30 for about a minute and then up 120. i checked it against my apple watch which had me at a steady 80-85. happy to change the review if i'm missing something in how i'm holding my finger over the camera
This has all that I need for using biofeedback to try to improve my training. It is basic but excellent value.
One improvement I'd like to see is better login handling. I've been randomly logged out recently for some reason, and it's a bit of a hassle to log back in. I would also like to see integration with password managers to make this process smoother.

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.

Love this app and what it does but data only syncs and saves for me about half the time. Possibly it’s just a hazard of rural internet but disappointing nonetheless
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.

Maybe HRV4BioFeedback is not working with iOs 16.3? Camera flash turns on, stays on, and no measurements take place at all, screens lock up.
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.
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.

I’ve used HRV4TRAINING for over a year.Recently, I listened to Marco‘s interview with Dr. Khazan, and decided to try out biofeedback. The app pairs well with Dr. Khazan’s book, and I’ve maintained a breathwork practice via the app for a a few weeks.
It took me a few weeks to realize the “Power” graph represented my breathing rate. Consider adding an additional label for the layperson such as myself.
I wonder if research shows that the optimal resonant frequency changes after some training, and if so, then the app could suggest retesting for your ideal frequency every two weeks or so.
I don’t own an Apple Watch, but have friends that do, and I’d like to recommend the app to them. You mention the watch doesn’t deliver live data, but is live data required? If the watch can store up to 20 minutes of HRV data, then send it to the phone for the app to process, doesn’t that work just as well? Even to find your resonant frequency, the app can change the visual breathing pattern, and match time stamps to sync up the frequencies to HRV.
Lastly, is it possible to allow the app to operate in the background? I’m using a consumer EEG with an associated iOS meditation app, and would be very curious to record my breathwork while simultaneously recording my brain waves.
Great work, sir. Cheers.

I’ve found this app to be incredibly valuable for measuring and managing my life stress.
Like an another reviewer said, it’s not really biofeedback if... there’s no feedback. Having a real time HRV number on the screen would bring this to 5 five stars for me.
Any one else get this?
It’s what I got when setting up the app. Registering an email and a password appears to be required.
I don’t have a Twitter account, so no contacting dear developer that way.
Did send an email to address listed in app.

Update:
Deleted and reinstalled app.
That seemed to work.

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.
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.
