Yudemon HRV is a unique visual and sonic tool for resonance breathing and HRV biofeedback training. It provides a fun and engaging workout for your autonomic nervous system, helping you build stress resilience and enhanced self-regulation. You can either use the app as a basic breath timer, or connect an ECG-based heart rate monitor (like the Polar H10) via Bluetooth for full biofeedback and analytics. Unless you specifically opt-in to cloud sync, all data processing happens on your device, so your data is completely secure. Using Yudemon with a heart rate monitor not only allows you to track and visualise your data for each session, it also enables you to use Yudemon's Journey Mode, a novel and unique way of establishing your own optimal breathing rate over the course of multiple sessions. Yudemon's adjustable visuals and soundscapes offer infinite variations, making every breathing session feel fresh and engaging. By default, the app’s appearance automatically changes on a daily basis. Or, with Yudemon Pro, you can take full control and customize everything manually. A healthy heart does not beat like a metronome but constantly adapts to the requirements of the present moment. Heart rate variability (HRV) biofeedback training and resonance breathing are based on the fact that our breathing has a direct impact on the rest of our physiology. By controlling our breathing in specific ways we can train our body to become more adaptable and perform better under stress. Yudemon helps you with this practice. Yudemon HRV is the first breathing app with custom soundsapes and functional music specifically designed for resonance breathing and HRV biofeedback training. The soundscapes guide you in your breathing sessions and aim to enhance the effects of the practice. It also integrates other aspects of generative art, such as the "Heartwork", a unique piece of art based on your very own physiological data that is generated and grows with you as you complete more sessions. New visuals, soundscapes, and effects are added on a regular basis. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/}

In addition to the cool visuals it’s the only app that can tell you resonance frequency in less than a .5 second interval. This can get up 10% closer to your real frequency compared to other apps.

Can we lower the range to support 3 breaths per minute? Thanks!

I’m learning about HRV and heart coherence, interested to see what my resonance frequency breathing is at different times of the day, if there’s one value I tend to be around. This app is hitting the nail on the head with helping me with that. Thanks for taking the time to do this, it is valuable ❤️

I initially gave this app 2 stars because it really wasn’t working and was requiring me to delete data. After communicating with developer. I have re-installed it (including a power down of my phone). I suspect the problem was related to the installation of the latest iOS? I don’t want to get technical about HRV Biofeedback (HRVB) so it suffices to say that this app is great! Furthermore, the fact that the developer communicated with me to solve the problem adds additional value.

Has a lot of well executed features (artwork / styling, soundscapes, journey mode*), but misses some essentials. - *Journey mode doesn’t converge here after 20 sessions - Can’t see the last Journey session average HRV - Data seems completely dominated by outliers - No way of seeing which Journey HRV plot segments were at which breathing rate - No way of seeing old session data - No way of tracking history in the total datapoint graph - No way of looking at session HRV over time when doing multiple a day - only shows daily averages. That said, I’m considering most of these essential because the data doesn’t appear properly filtered, and I’m trying to debug what’s going wrong. Having a single sigh / yawn / bit of movement in a measurement will cause a peak in the HRV and seems to make it choose that direction for the next Journey step, instead of filtering those out and looking at the stable bits of data. There are a couple of papers on outlier filtering in HRV measurements, having some more of that implemented would make it a great app

This is a well thought out app for finding your optimal HRV based on science and individual testing. The testing methodology seems spot on. You can see your stats and learn from them if you so choose. Thus far, if you want to know your optimal HRV, this one is my favorite. I have tried a bunch of them. I now feel that I do not need to keep looking for more “Optimal HRV” apps. Of course I wish it was free, but there was a great amount of time and effort put into the app. Knowing what I know now about it, I would spend the $20 here first, before the other ones I have tried.

Interesting app for HRV biofeedback (HRVB) and with unique algorithm for establishing resonance breathing frequency. Recommend to try.
