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. Free plan - 1 JSON source - 2 complications - Circular and rectangular widgets - 15-minute refresh Complica Pro (one-time unlock) - Unlimited sources and complications - All complication families (adds inline and corner) - Custom refresh intervals down to 5 minutes - Custom units, min/max, gauge ranges - HTTP headers for private or authenticated endpoints Privacy No accounts. No tracking. No analytics. No ads. Your URLs and configuration stay on your device and your paired Watch.

Verdict
The clearest difference is in-app purchases: Complicator at none against Complica's 1. Complicator also leads on update cadence (weekly vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
