4/5Good 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.

5/5Excellent 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.

3/5Useful 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.

5/5Incredible
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.

5/5Amazing 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.
