Rhythm

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.

  OwnTime – a chess clock for your day's priorities▲110

  I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
