Overhead

Even G2 HUD app that shows the nearest aircraft over you, sourced from adsb.lol.

What it does

• On launch, draws a "scanning..." page on the G2 HUD.
• Asks the Even App webview for the phone's GPS (navigator.geolocation), falling back to the last cached coordinates in Even App local storage.
• Queries https://api.adsb.lol/v2/lat/{lat}/lon/{lon}/dist/10 for aircraft within 10 nautical miles, picks the closest, and renders: FLIGHT / TYPE · ALT · SPEED / DISTANCE / tap to refresh.
• Tapping the first text container (CLICK / DOUBLE_CLICK on the G2 touchpad) triggers a refresh.

Stack

• TypeScript + Vite
• @evenrealities/even_hub_sdk for the page-container bridge to the HUD
• Plain fetch to api.adsb.lol (no API key)

Develop

npm install
npm run dev      # vite dev server on :5174
npm run build    # tsc + vite build to dist/
npm run typecheck

To run on glasses, point the Even App at the dev URL (or upload dist/).

Open questions / v0 limitations

• Webview geolocation permission has not been verified on the Even App yet — if getCurrentPosition is denied, the app falls back to cached coords; no UI to set them yet (manual setLocalStorage('overhead.lastCoords', ...)).
• No route lookup (origin → destination): adsb.lol doesn't carry it.
• No auto-poll: tap to refresh only.
• No image budget used: text-only HUD.
