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 Service: https://app.yudemon.com/terms Privacy Policy: https://app.yudemon.com/privacy

About

Breath

Features
Read full description

Breath is a guided breathing timer for one practice: slow, even breathing at about 5.5 breaths a minute. That rate is known as resonance breathing, or coherent breathing, and it is the pace used in HRV biofeedback. Two audio tracks ship inside the app, one short and one long. You open the app, tap one of two circles, and it begins. There is nothing to configure. HOW A SESSION GOES Each breath cycle lasts 11 seconds, about five and a half seconds in and five and a half out, cued by soft tones over an ambient bed. The audio keeps the rhythm, so there is nothing to count. Tap once during a session and the screen fades to black while the audio and the timer keep running. Eyes shut, or the phone face down. Tap again and it comes back, slowly. Audio continues when you lock the phone or switch apps. END finishes early, fading the audio out. A session under one minute is discarded. WHAT IT KEEPS Six weeks of practice as a quiet grid of dots, with your current streak, your total minutes, and your recent sessions. With your permission, each session is written to Apple Health as a Mindful Session. The Health permission is write-only. Breath asks for no read access at all, so it cannot see your heart rate, your heart rate variability, or anything else in Health. PRIVACY Breath collects nothing. There is no account, no analytics, no advertising, no third-party code, and the app makes no network requests of any kind. Both tracks are bundled inside the app, so it works in airplane mode. Your practice records stay in the app's own storage on your device. ABOUT THE RHYTHM Your heart rate already rises and falls with every breath you take. Breathing at about one cycle every eleven seconds, roughly 0.09 Hz, puts each breath in time with a rhythm the body already has, and the amplitude of heart rate variation reaches its maximum right there. That much is measurable, and it is why paced breathing at this frequency underlies HRV biofeedback. Whether it produces lasting change is a separate and less settled question. Breath keeps the rhythm and leaves that open. Breath is a breathing timer. It makes no medical claims, and it does not diagnose, treat, or prevent any condition.
