A focus timer for the Spotify Car Thing, with a shelf of swappable visual designs. Turn the wheel to set the time, press to start, hold to stop.

Thirteen designs

Switch skins any time from the on-device picker. They share one timer and one history — only the presentation changes.

What it does

A full Pomodoro cycle on a 5-inch screen you drive with one wheel.

◒One-wheel control

Turn to set the minutes, press to start, pause or resume, hold to stop or skip. Three preset buttons for 15, 25 and 45.

▢Pomodoro sets

Four focus sessions to a set, short breaks between, a long break at the end. Focus flows into its break; breaks stay exact to the second.

⏴History & streaks

Every session is logged on the device — daily focus totals, the busiest day, and your running streak, a week at a time.

⏱Clock that tells the truth

The Car Thing has no battery clock. The app checks it against your phone and the boot id, and warns instead of logging against a wrong time.

▦Thirteen designs

From a calm e-ink page to a DOOM corridor to an Airbus cockpit — one timer, many skins, swapped in a tap.

Runs on bridgething

bridgething turns the discontinued Spotify Car Thing into a programmable device: a daemon serves small web apps and exposes a typed client SDK that a webapp uses to talk to the hardware over a local WebSocket. This project is one such webapp — it uses the daemon's store for persistence, the time surface to check the clock, system diagnostics, capabilities and audio for the completion chime.
