Rhythm
Today: cognitive peak at 10, slump at 3, last coffee by 1:15
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.
