Nami - Biofeedback & HRV 앱 분석 (9월 23일)

Nami – Biofeedback & HRV Nami helps you watch your heart signals while you breathe. It can use a Polar heart rate sensor, your phone camera, or the microphone to show your heart rhythm on the screen, helping you practice calmer breathing and keep a record of your sessions. For deeper use, Nami also includes HRV metrics, real-time charts, breathing guides, biofeedback games, custom web experiences, phonocardiogram tools, session history, and data export. See your heart rhythm. Train breathing with feedback. Explore your signals over time. REAL-TIME BIOFEEDBACK Nami shows live physiological signals during each session. Instead of only giving you a final score, Nami lets you see how your heart rhythm and breathing response change in real time. This makes practice more intuitive, because you are not just following instructions — you are observing your own response. BREATHING AND HRV TRAINING Use Nami to practice breathing with real feedback from your heart rhythm. You can follow guided breathing sessions, observe rhythm changes, train coherence, and review how your signals changed during each session. HEART RHYTHM AND HRV METRICS Go beyond basic heart rate. Nami lets you explore heart rhythm and HRV metrics such as: • RR intervals • BPM • RMSSD • SDNN • pNN50 • SDSD • LF/HF ratio • coherence • frequency-domain views These metrics help you observe patterns across sessions, compare averages, and understand how your signals change over time. MULTIPLE SENSOR OPTIONS Choose the sensing method that works best for you: • Polar and compatible Bluetooth heart rate sensors • phone camera pulse sensing • finger-on-camera mode • microphone-based heart sound observation • supported wearable and external flows No single sensor is required for every use. You can choose the setup that fits your session. PHONOCARDIOGRAM EXPERIENCE Use the microphone to explore heart sound patterns. Nami includes a phonocardiogram experience with waveform and spectrum views, helping you observe heart sounds and signal behavior in a visual way. BIOFEEDBACK EXPERIENCES Nami is more than a chart screen. You can choose different session experiences, including: • free real-time signal sessions • guided breathing • phonocardiogram • biofeedback games • custom web experiences This makes Nami useful for personal practice, experimentation, education, and research-oriented workflows. CUSTOM WEB EXPERIENCES Open a custom webpage during a session and combine it with live physiological feedback. This can be useful for custom protocols, learning tools, experimental interfaces, guided content, or external biofeedback workflows. SESSION HISTORY AND DASHBOARD Each session becomes a record you can review. Nami lets you see session averages, trends, body markers, state before session, detailed graphs, samples, and recorded signal behavior over time. DATA EXPORT Export your session data when you want to analyze it outside the app. Nami is designed for users who want control over their data, from simple breathing practice to deeper signal exploration. CONFIGURABLE FOR ADVANCED USE Nami includes settings for sensors, charts, breathing pacing, runtime displays, session behavior, data recording, and export. It can be simple when you want a quick session, and flexible when you need more control. PRIVACY • no account required • your data stays on your device • optional Google login • no unnecessary data sharing IMPORTANT NOTE Nami is not a medical device and does not provide diagnosis, treatment, or medical evaluation. Results depend on sensor quality, signal conditions, and proper use. Nami is a biofeedback and self-observation tool for breathing practice, HRV exploration, heart rhythm awareness, physiological signal tracking, and configurable real-time feedback sessions.
