A personal map that reveals the world as you explore it — like fog of war in an RPG, but for real life.
Log places you've been and watch your map come alive. The more you've explored a neighborhood, the more the fog lifts.
Your data lives in an encrypted vault file on your device — no account, no server-side personal data. Open your vault to load your map; save it when you're done.
Use the Wuz Here button to add places you've been:
- GPS — one tap to mark your current location
- Photo — select photos from your camera roll; GPS and timestamps are read from EXIF metadata locally, clustered into places, and logged (nothing is uploaded)
- Search — find any place by name and pick the date you visited
- Import — bulk import your Google Maps Timeline export (JSON) for historical data
In the World view, each neighborhood you've visited appears as a soft fog reveal — brighter the more you've explored it. Click a neighborhood to enter the Area view, where the real neighborhood boundary becomes a dungeon wall and your visited spots clear the fog inside it.
Create quests with a list of tasks to complete around the world. Tasks can be tied to a location — when you use Wuz Here nearby (within 100m), the task auto-completes. Share quests with friends as a link or a file; the full quest is encoded in the URL so it works without any server or session.
