TraceMap

A fog-of-war exploration app for iOS and Android. Your map starts fully fogged — live GPS clears an organic, blob-shaped radius around you as you physically walk or run, permanently unlocking that area on your account.

• —Live circular fog-of-war reveal that follows your actual walked path
• —Speed-based movement detection — walking and running clear the map, driving doesn't
• —Stats on % of your city explored, plus your city-wide rank
• —Friends and city-wide leaderboards
• —Animated post-session recap replaying what you revealed
• —Hidden rewards placed along real-world routes
• —Account-based, cross-device persistence

Built to work standalone on phones first, with an eye toward a future companion view on Meta Ray-Ban Display smart glasses.
