Roamly Offline
An AI trip planner that builds a complete day-by-day itinerary from OpenStreetMap data and runs fully offline once downloaded, so international travelers never need roaming data to navigate a new city.

- Auto-built daily itinerary from nearby OSM points of interest
- Offline turn-by-turn walking and transit routes with voice cues
- Strict no-tracking mode: no accounts, no telemetry, on-device itinerary cache
- Battery-aware GPS that throttles when screen is off on long walks
