Trailfog

Trailfog is a lifelong fog-of-war footprint tracker. The whole world starts covered in fog. Walk somewhere — once — and the fog clears there, permanently. Over months and years, your own map slowly lights up with everywhere you've actually been. RECORD Open the app and it drops you straight onto your current location — no loading screen, no setup. Tap once to start recording, and the fog begins clearing in real time as you walk. Switch between daily, weekly, monthly, yearly, and lifetime mileage with a single tap. REPLAY Every session you record can be replayed later. Watch your route grow back at a steady pace, alongside a real 3D rolling globe that turns as you move — it feels like walking it all over again. PRIVATE BY DESIGN Your data stays on your device by default. Want it to follow you across devices? Flip on iCloud sync in Settings — your history is stored only in your own private iCloud database. Trailfog has no ad SDKs, no analytics trackers, and no backend server of its own. Nothing is ever sold or shared. NO SOCIAL FEED. NO LEADERBOARD. Trailfog isn't for showing off where you've been. There's no feed, no friends list, no check-ins. It's a private, permanent record — just for you.
