## What is Yudemon HRV?

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.

### 5/5 — Nothing comes close.

*2026-08-04*

I’ve tried most if not all of the HRV apps out there. This is what all of them should be. It’s what I was wishing I could make for myself before I found it. The journey feature is unique to this app and in my opinion is what propels it leagues ahead of the next best. 

I’m grateful for it and even moreso that it keeps getting updated with better and better functionality.

### 5/5 — I neeeed this

*2026-07-29*

This is exactly the app I need in the fresh Hellsescape that is 2026. Thanks buds for doing what you do.

### 5/5 — Best HRV App by far

*2025-09-18*

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.

### 5/5 — Needs to support <4 breath interval

*2025-05-16*

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

### 5/5 — Great HRVB

*2024-09-21, version 2.8.0*

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.

### 2/5 — Buggy with poor user instructions

*2024-09-18, version 2.8.0*

The idea of this app really appeals to me.

However, there is a dearth of advice on how to use it - no help section. Furthermore when I did "work it out" if freezes at the section where I should be repeating my daily/ twice-daily journey. The only way I can stop this is by deleting previous data i.e. re-installing the app. 

I have recently updated my iOS to 18.0, perhaps the app is not optimised for this?

### 5/5 — Don’t change anything. It’s perfect

*2023-11-30*

Don’t change anything. It’s perfect. Please

### 4/5 — Too buggy but very promising

*2023-08-01*

Too many bugs (end screen and stats screen)and artifact filtering needs improvement. Very promising concept though. Kudos to the developer.

### 5/5 — One of the best, my personal favorite

*2023-04-05*

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.

### 5/5 — Beautiful experience

*2022-06-29*

Yudemon functionality is very simple but yet you can get a very beautiful experience right away. The free version is already very pleasant to use. The subscription (very affordable) gives you access to authoring both the visuals and the soundscapes, and the options are very well curated.
