Walk to reveal your map
The world starts covered. Every street, park, and neighborhood you visit stamps a hex tile and uncovers the map beneath — your own fog-of-war over the city.
Track how much of your city you've explored, from single hexes to whole countries.
Pin memories to places
Tap any hex you've stamped to name it, jot down what happened, and attach photos. The place itself holds the story — not a camera roll you'll never scroll back through.
"Satay by the sea." "Saturday kouign-amann." Your map becomes a journal.
Follow where friends have been
Add friends by phone number and, once you both approve, see each other's stamped tiles and memories — on the map and in a feed of real places, not posed posts.
Discover the corners of your own city that your friends already love.
We store hexes, not your GPS trail.
Your movements stay yours
When you stamp a tile, m.app records only an H3 grid cell identifier — a coarse hexagonal area — never your raw GPS coordinates or a continuous movement trail. Read the details in our Privacy Policy.
