Filling Bird

Walking & exploration · iPhone

See where your walks take you.

Record a walk and watch the map fill, one hexagon at a time. Keep the places you discover, follow your progress, and connect your routes with a team.

A closer look

A walking map with visited areas, saved places, badges, and optional team progress.

A map of your own

Walking turns new map cells into a visible record of the ground you have covered.

More to discover

Explore visited regions, review daily progress, and work toward badges as your map grows.

Places worth keeping

Save a park, café, or viewpoint with notes and a photo so you can find it again.

Your progress, in the picture.
