A single-file, offline-first GPS navigation app built entirely with HTML, CSS and JavaScript. No app store, no account, no tracking — just open gps6.html in any modern mobile browser (e.g. Vanadium/Chrome/Firefox) and start navigating.
- Live GPS tracking — auto-starts on load, shows your position and heading on an OpenStreetMap map
- Search & POIs — search cities, streets and places (Photon geocoder), or tap the 🏪 button to browse nearby POIs (restaurants, fuel, parking, hotels, pharmacies, ATMs, sights…) fetched from Overpass/OpenStreetMap
- Turn-by-turn navigation — set a destination, get a full route with:
- 🚗 Car or 🚶 Walking routing (OSRM + automatic Valhalla fallback when the OSRM servers are offline)
- Route preference: ⭐ Best, ⚡ Fastest, 📏 Shortest
- Automatic rerouting if you leave the route
- Full-screen 3D driving view — pseudo-3D perspective road view with junctions, side roads and a turning arrow, plus ETA and distance-to-turn HUD
- Voice guidance — spoken instructions at key distances:
- 🔊 System voice (device TTS)
- 📡 Online voice (Google Translate TTS — works even on de-Googled devices where system TTS is silent)
- 🔇 Muted
- Slide-down menu — all extra controls tuck into a compact ☰ menu so the map stays clear in portrait mode
- Persistent settings — your voice mode, transport mode and route preference are remembered between sessions
- Wake lock — keeps the screen on while navigating
