the world is unmapped until you walk it

Your map starts dark.
Walking turns it on. Forever.

FOG is a fog-of-war map of your real life. Every street you walk is revealed for good — your city, your travels, your whole world, drawn in light you earned on foot.

How it works

Walk. Reveal. Keep it.

No setup, no goals to configure, nothing to maintain. Open the door and the map starts paying attention.

i.

Walk anywhere

The fog burns away wherever you pass — and stays away. Every errand becomes territory.

ii.

Collect the world

Cross into a new country, region, or landmark and it joins your collection. Pokémon, but the Pokédex is Earth.

iii.

Earn your rank

From Fogbound to Atlas — ranks are paid for in kilometers, and only walking counts.

FOG share card: a walked trail drawing the world map in glowing dots
The proof

Your trail draws the world.

Every clearing on your map is somewhere your feet have actually been. Stack enough of them and the trail itself becomes a map of your life — one glowing line at a time.

One tap turns it into a share card. Brag responsibly.

A statement from the fog

FOG does not track you. FOG simply hides the world until you walk it. That's the whole app.

No account. No analytics. Your map never leaves your phone — we couldn't look at it if we wanted to.
No streaks, no timers, no events. Nothing to lose at 11:43pm. The world just stays open.
Nothing to rent. One purchase unlocks everything, once — like buying a shovel, not renting one.
Yours, permanently. Export your map anytime. If we vanished tomorrow, it would still be on your phone.

The map is waiting.
It's mostly fog. That's the point.
