HRV4Biofeedback App Reviews

Super valuable. I’ve found this app to be incredibly valuable for measuring and managing my life stress.

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

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.

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.

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.

“Registration Failed [-1001]”. 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.

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.

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.

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.

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.

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.

Mostly love it but lots of lost data. 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

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.

Update killed it?. 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.

Not really biofeedback. 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.

Works great; feature requests.. 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.

Great Biofeedback App. This is a great app for learning about and measuring your heart rate variability and works with the camera on your phone. It uses a breathing exercise to measure and improve your heart rate variability, which is an indication of the health of your nervous system. The breathing exercise can be customized to your preferences. There’s heaps of additional information available and the app developers got back to my query straight away!
