Intensity & Timer

Live Stimulation Control.

Start a session from here and the same circle tracks the countdown and your live heart rate for as long as it runs.

Raise or lower intensity one step at a time, each change confirmed before it takes hold.

The 30-minute timer counts down while a live heart-rate graph runs beneath it.

Stop ends the session outright, and up to 10 attempts are tracked here each day.

Sleep Analytics

Daily heart rate & sleep tracking.

The main screen keeps a live PPG reading, today's stimulation count, connection status, and battery in one place.

See your heart rate and stimulation history on a daily and weekly basis.

Daily view shows the sleep score you gave the night yourself, today's stimulation count, and average heart rate.

Weekly view gathers the daily data into a longer trend in sleep efficiency.

How to Use

5 Steps from Unboxing to Sleep.

Insert, pair, choose your level, and let the timer finish it.

Insert

Insert BeCozU into your ear, so the electrode contacts rest comfortably against the outer ear.

Pairing

Pair the earbuds in your phone's Bluetooth settings first, then connect inside the app.

Configure Your Session

Set the intensity in the app: 10 levels, one step at a time. Start low, and raise it only if you want to.

Start Session

Use for 15 to 30 minutes, before bed or during a midday break. Elapsed and remaining time stay on screen.

Monitor Progress

Track your daily and weekly trends in the app dashboard.
