Are you feeling stressed, burned out, or just not yourself? Optimal HRV is the guided biofeedback app that teaches your body to calm down — for real. Backed by a Harvard Medical School mindfulness expert and trusted by athletes worldwide. Optimal HRV pairs real HRV data with live biofeedback, so every session trains your nervous system to handle stress better — not just tells you that you're stressed. Why HRV and Biofeedback Training Work Your Heart Rate Variability (HRV) is a window into how well your body handles stress, anxiety, and recovery — and biofeedback is how you train it to improve. Together, they show you what's happening inside your body, then guide you to change it in real time. With Optimal HRV, you can: • See how stressed — or relaxed — your body really is, using real HRV data. • Learn what actually helps you recover, from sleep to workouts to busy workdays. • Use live biofeedback to train your body to relax faster, right as it's happening. • Discover your own personal "perfect breathing rhythm" through guided sessions. Features You'll Actually Use • Daily Check-Ins — take a quick reading each morning, or anytime you want to see how you're doing. • Your Perfect Breathing Rhythm — a simple test finds the exact breathing pace that works best for you. • Live Feedback While You Train — a simple on-screen guide shows you when you're doing it just right. • Calming Mindfulness Sessions — guided practices created with a Harvard Medical School mindfulness expert, covering stress, anxiety, pain management, athletic performance, and more, with calming narrations in your choice of voice. • Easy-to-Read Progress — see your trends over days, weeks, and months, no data expertise needed. • Video Tutorials — learn HRV concepts and techniques at your own pace. • Make It Yours — adjust sounds, pacing, and reminders so training fits your life. • Available in 14 Languages — use Optimal HRV in your native language. • Device Testing — quickly verify if your heart rate monitor works with the app. • Great for Teams Too — employers and coaches can track group wellness together (Dashboard access needed). Why Optimal HRV Works with External Sensors (Not Apple Watch) We choose precision over convenience. Apple Watch is great for daily wellness, but Optimal HRV is built for serious HRV training. That's why we connect directly to an HRV monitor via Bluetooth — they deliver millisecond-accurate R‑R intervals that wrist sensors can't match. What that means for you: • More accurate data – better insights, better decisions. • Real-time streaming – no gaps, no guesswork. • Reliable results – trusted by athletes and coaches worldwide.

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
