I wanted my plan within sight without opening another laptop tab or reaching for my phone. TrevOS puts that idea on a small desk puck: turn the dial, choose a task, and stay with it. Built for the Waveshare ESP32-S3-Knob-Touch-LCD-1.8 hardware family, its shared shell and design system host Pomodoist for Todoist focus sessions and Cal for a calendar glance. Makers can build the whole device or adapt one app.
