Complica

Apple Watch complications are mostly hardcoded to specific apps. Complica is different. Point it at any JSON URL, map the values you want to display, and show them on your watch face. Requires a paired Apple Watch.

Use it with anything that returns JSON: a weather API, a stock or crypto ticker, a smart-home sensor, server health, your own backend, a hobby project. Values refresh in the background and appear live on your face.

How it works

1. Add a JSON source (paste a URL).
2. Pick a complication style - circular, rectangular, inline, or corner.
3. Map JSON keys to fields like title, value, gauge, icon, color.
4. Add the complication to your watch face.
