Breathing, coherence, and HRV biofeedback in real time

Features & Capabilities

Nami – BPM, HRV & Breathing is a high-precision Chrome extension that measures heart rhythm and breathing in real time, with full signal visibility and no black boxes. See your heartbeat, analyze HRV, and practice breathing with an adjustable pacer—all offline and private with no cloud accounts. Graphs help you explore data beyond numbers, making it suitable for both casual users and researchers.

Core features include beat-by-beat heart rate, HRV metrics (RMSSD, SDNN, LF/HF), a breathing trainer with customizable pacing, and biofeedback tools. You can export data as CSV, use multiple user profiles, and view interactive, zoomable graphs. Optional sensor options cover built-in mic, BLE straps (Polar H6/H7/H10/H01), experimental camera mode, and Wear OS support. Two modes—Pacer and Game—support breathing practice in relaxing or focused contexts. The app emphasizes privacy: fully offline with no accounts or cloud sync, and transparent pricing with ads and a one-time upgrade option. Note: Nami is not a medical device; results depend on sensor quality and usage.
