Works perfectly
Not sure why other peeps cannot use it, works perfectly for me with all the features as described. Got it in the package with all the other apps! Marco has really good tips on his blog, insightful!
Doesn’t work
I wanted to try resonance breathing. Saw this on Reddit.
This app doesn’t work at all.
Save your $10. Use another app like Elite HRV or Optimal HRV.

heart rate varies wildly
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
Do not use
It is not possible to log into their portal to get the data. Last blog entry was 2021. I doubt they are still actively supporting their app
Marche tres mal
Bugue sans arret. Le feedback ne se fait pas en temps reel donc impossible de savoir ce qui fonctionne. Mauvais achat
NOT WORKING :(
I tried EVERYTHING, but I have to registrate- and that is not possible. It always says: ERROR 200
I spent 9,99 € for anger and not for relaxation.

Excellent app, but could use some updates
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.

My second review
One of the best health apps.
It has helped me increase my hrv be mindful of my breathing throughout the day.
Doing two 20 mn sessions a day was needed to get to that point.
One thing that is missing is an audio cue for people with bad vision or that dont want to look at the screen especially at night.

I am surprised…
I am surprised how quickly the biofeedback session brings me to the present moment. Which means I am in a calm state . It happens within a minute . I wasn’t expecting it . I have practiced meditation ( 11 minutes) , hypnosis ( Reveri by David Spiegel of Stanford) , PQ reps ( Positive Intelligence by Shirzad Chaman of Stanford) and this method gives results the quickest.

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.

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
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.

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.
Nice app!
Thanks to this app, I am able to do a daily HRV feedback session and see my progress over time🤩
Thanks Marco for a very reasonably priced and well designed app!!

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.
Best App for HRV insights.
Beautiful and data driven for HRV improvements.
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!
