CerebroSync turns a Muse 2 headband into a clear, live view of a single session — no laptop, no lab software, and no raw EEG to interpret on your own. Pair the headband over Bluetooth and the app decodes its sensor packets directly on your phone. You see electrode contact for all four channels, a live EEG trace, relative power across the delta, theta, alpha, beta, and gamma bands, a pulse estimate, breathing pace, and head motion — each labeled plainly so you always know how much to trust the reading in front of you. WHAT YOU GET • Direct Bluetooth LE connection to a Muse 2 — no bridge software or desktop app required • Four EEG channels at 256 Hz: TP9, AF7, AF8, and TP10 • Per-electrode contact quality, so you can fix a poor fit before you record • Relative band power computed on the phone, in real time • Pulse and breathing pace estimates from the headband's optical and motion sensors • Motion and rotation artifact flags, so noisy stretches are obvious • A three-light session readiness summary: calm, elevated, or review • Headband battery and stream health at a glance SESSION HISTORY Switch on cloud recording and CerebroSync saves a compact checkpoint once a minute — band summaries, contact quality, pulse, and the readiness label — to your private account. Raw EEG never leaves the phone. Switch it off and everything stays local to the device. BUILT FOR CLARITY Four tabs, no clutter. Device connects the headband and monitors the stream. Signals shows the evidence behind the current reading. Model explains what the processing pipeline actually does. Setup holds your profile, session notes, and recording preferences. PRIVACY Your sessions belong to you. Accounts use email and password, session data is scoped to your account alone, and nothing is sold, shared, or used for advertising. WHAT YOU NEED • A Muse 2 headband (sold separately by InterAxon) • Bluetooth turned on • An account created in the app IMPORTANT CerebroSync is a wellness and education tool, not a medical device. Contact quality, pulse rate, breathing pace, and the calm / elevated / review label are prototype estimates, not clinical measurements or validated classifications.
