Explore the world. Unlock your map.

how it works

go somewhere. the fog remembers.

There's nothing to log and nothing to check in to. Carry your phone, and the places you pass through stay uncovered.

01 / MOVE

every route leaves a trail

Your commute, a detour, a new city. Each stretch of road you cover clears the fog behind you, in the background, without the app open.

street-level view: small hexagonal tiles cleared along the streets that have been walked, fog over the blocks that haven't
02 / ZOOM

three scales at once

Micro tiles for streets, minor tiles for neighborhoods, major tiles for whole regions. One step outside unlocks all three.

light up the flags

Set foot in a country and its flag lights. 195 to find. Thousands of cities keep a percentage of their own.

the countries page: a grid of national flags, the visited ones lit and the rest dim, with a count of nations touched
an area replay in progress: a framed section of the map where tiles light up one by one in the order they were discovered, with a counter and a timestamp

tile replay

Minor and macro boards alongside the free micro board.

No ads

And Entry Mode, for adding past travels by hand, without watching one.

Monthly, with a 3-day free trial, or a one-time lifetime purchase. Billed by Apple.

the rules

your travels are yours.

A map of everywhere you've been is personal. The app is built around that.

on your phone

your map stays on your device.

The tiles you unlock are stored on your phone. Friends you add see tile counts, and nothing about where those tiles are.

earned on the ground

flights don't count.

Tiles unlock at the speed of roads and trails. Pass over a country at cruising altitude and it stays fogged until you land.

yours to keep

export it any time.

Save your whole map to a file whenever you like, and restore it on a new phone. No sign-up, no email, no password.
