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

SYM BREATHING A simple way to slow down, breathe evenly, and find a calmer rhythm. Sym Breathing guides you through a balanced 5.5-second inhale and 5.5-second exhale using smooth visual, audio, and haptic cues. This slow, even rhythm is commonly known as coherent breathing or resonant breathing. Choose a session length, tap the breathing sphere, and follow along. No complicated routines. No overwhelming controls. Just a simple breathing practice you can return to whenever you need a few quiet minutes. GUIDED BREATHING, YOUR WAY Follow the expanding and contracting breathing sphere, listen for gentle audio cues, feel subtle haptic feedback, or combine all three. Choose the guidance that works best for you and your surroundings. A SIMPLE, BALANCED RHYTHM Sym Breathing uses a 5.5-second inhale and 5.5-second exhale, approximately 5.5 breaths per minute. The app keeps the rhythm for you, so you can focus on breathing instead of counting seconds or watching a clock. CHOOSE YOUR SESSION Select a breath count for a defined practice or choose an open-ended session and breathe for as long as you like. DAILY AFFIRMATIONS Begin with a daily affirmation that offers a brief moment of positive reflection before your breathing practice. NIGHT MODE Switch to a warm red interface for a softer visual experience in low-light environments or before bed. LISTEN TO YOUR OWN AUDIO Keep listening to music, ambient sounds, podcasts, or other audio while you breathe. Adjust the breathing cue volume independently to create the experience you prefer. COHERENT BREATHING Slow, balanced breathing practices are commonly used for relaxation, mindfulness, stress management, and supporting autonomic regulation. Research has also explored resonant breathing in relation to heart rate variability, or HRV. Sym Breathing makes this practice easy to follow by guiding each inhale and exhale for you.
