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 slow rotation, a ticker along the bottom. It is meant to be seen from across the room, not read.
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.
Self-hosted today: single container, one SQLite file, on your own machine. A hosted option — somewhere for a Watch to send data without running a server — is what is still being worked out.
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.
Setup
A browser is genuinely enough — Plash and Fully Kiosk below are conveniences, not requirements.
F11 on Windows and Linux, ⌃⌘F on macOS.chrome --kiosk <url> — on macOS, open -a "Google Chrome" --args --kiosk <url>.Displays are ordinary web pages, so anything that can hold one open works: a Raspberry Pi on a monitor, a retired iPad, a Fire tablet, the browser built into a TV.
Configuration
Heartbeat 3000 isn’t hosted yet, so there is no /setup page to build the URL for you — add parameters to the bare URL by hand, as documented in the README that ships with it.
| Parameter | Default | Meaning |
|---|---|---|
/ | — | Normal rotation, 12 seconds a panel. |
panel | — | Pin one panel: current, overnight, forecast, scan, or an index 0–3. |
panels | — | Rotate through a comma-separated subset, in the order given. |
cycle | 12s | off stops rotating; a number changes the dwell time in seconds. |
/body | — | The full subject record — every metric on file, sleep log, workout log. |
dim | 0 | Black scrim over everything, 0 to 0.8 (fleet-wide convention). |
Heartbeat 3000 is open source under the MIT licence. Run it yourself with one command — the repositories go public at launch.
