Yudemon HRV vs Hummingbird Biofeedback

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

Hummingbird Biofeedback reads the Bluetooth signal your heart-rate strap (Whoop, Polar H10, Garmin HRM, …) is already broadcasting and shows live HRV, beat by beat, on your screen. No server. No account. The strap you already own, finally fully visible — alongside real-time biofeedback for humming, meditation, breathwork, or simply sitting still. Pick a humming pattern and a pitch target moves across the screen, you hum along, and three live readouts update underneath — a real-time picture of what your nervous system is doing, not just one number. — WHAT YOU WATCH, LIVE — HRV 5-minute rolling rMSSD — the same metric used across the HRV ecosystem. Different moment of the day than your nightly score, same math. RSA Vagal depth. Every breath stretches and releases your heart rate; RSA measures how big that swing is, in milliseconds. It's the amplitude of your breath's pull on your heart — and slow, deep humming widens it. Watch it widen, breath by breath. COHERENCE Rhythm, on a 0–100 scale. How clean and orderly that wave is. When your breath and heartbeat settle into one smooth oscillation, coherence climbs toward the resonance "zone" — the difference between a flute holding one clear note and a radio stuck between stations. Why three and not one? HRV alone is jumpy, and during slow breathing it can even dip — even as the rhythm underneath gets deeper (RSA) and cleaner (coherence). The extra two metrics catch what a single number misses, so you can watch a session take shape in real time instead of guessing. What does five minutes of slow humming do to these numbers right now? What about fifteen minutes of meditation? Hummingbird is the simplest answer. — FIVE HUMMING PATTERNS — UNWIND Slow descending hum, the most-studied pattern. DRIFT Long, narrowly-descending hum with a lullaby-shaped contour. ANCHOR A held, steady pitch at a slow cadence. RESONATE Pitch and pace near the cardiovascular resonance band (~6 BPM). EXPLORE Free-form humming — no target, no prescribed cadence. — PLUS STILLNESS — Silent, mic-free biofeedback for any quiet practice — meditation, yoga nidra, body scan, pre-sleep wind-down, post-stress reset. No pitch target, no prescribed cadence. A passive expanding ring paces ~5.5 breaths/minute if you want an anchor; ignore it and the session still captures HRV, RSA, and coherence either way. Pick a 5, 10, 15, 20, or 30-minute timer (or Open) and tag the session with what you actually did, so a 6-ms rMSSD rise after "Pre-sleep" and a 6-ms rise after "Cold plunge" stay sortable in your history.
