FOG
Play by walking

A walking game about exploring the real world

Most walking games reward steps. FOG rewards new ground. The world is covered in fog, and the only way to play is to go somewhere you have not been.

The game

Every place on Earth starts under fog. Walk, and the fog burns off around you, permanently. Your score is the ground you have uncovered, and the board is the real world. Walking the same loop again does nothing; a new street does.

That one rule changes how you walk. Shortcuts become detours, errands take the long way, and trips become a chance to clear a whole new patch of map.

Progress

No grind, no pressure

There are no streaks to break, no daily quests and no ads. FOG runs in the background, so a walk counts whether or not you open the app. Two character paths and the ranks up to Scout are free. FOG Unlimited, a single purchase with no subscription, opens the other three paths, every rank and history import.

Private

No account, no cloud. Your trail stays on your phone, and you can export it as GPX. It is a phone app, on iOS and Android. For the idea behind it, see what a fog of war map is.
