Heartbeat 3000

Your vitals as a late-night broadcast. Heartbeat 3000 takes the data your Apple Watch already collects and plays it back as a mid-80s scope terminal — phosphor green on black glass, four panels on a twelve-second rotation, a ticker along the bottom. It is meant to be seen from across the room, not read.

Where the data comes from

Health Auto Export on iOS posts your Apple Watch metrics on a schedule. Heartbeat stores them and draws from its own copy — nothing is pulled from a third party while the display is up.

Where it runs

Self-hosted, single container, one SQLite file. It sits on your own machine or server; your health data never leaves it.

What it wants

A 16:9 screen you are not otherwise using. It scales as one unit, so it reads the same on a 5K monitor and a wall-mounted tablet.
