What it does
The mid-afternoon slump isn't a personal failing — it's your body keeping time. Rhythm reads your sleep and movement data and draws your day as one energy curve: your morning light window, your focus window, the dip, your last coffee, tonight's bedtime, each with a time on it. The windows aren't just a forecast — followed, they move the clock itself: morning light, an earlier last coffee, and a dimmer evening can pull sleep onset earlier and protect its quality.
Rhythm turns sleep and recovery data into practical guidance for the day ahead. Join the iPhone beta interest list and help shape what comes next.
