Close the loop
Run, walk or ride. When your route crosses itself, the enclosed territory is yours.


The streets you know. Completely new challenges.
Explore your neighborhood, grow your grund, collect points, and give every move a new purpose.

Run, walk or ride. When your route crosses itself, the enclosed territory is yours.
We divided the city into hexagons. Claim them, defend them and take over others’ cells.
You earn points even without enclosing territory. GRUNDO rewards everyone.

GRUNDO turns movement into a game on a real map. Walk, run or ride, enclose an area, and claim the cells inside. Strengthen your territory and defend it from other players!

Plan one-way routes or round trips. Choose a detour, route style and terrain, or ask Grout, the GRUNDO assistant, for help. Even your daily commute can become a new discovery.

Other players can take the grund you have claimed. The GP points you earn from activity track your long-term progress and are never lost. Follow your level, weekly activity and build your streaks, even when you haven't closed a new loop.

Explore the community, check the rankings, and create or join a band. In GRUNDO, movement can be an individual or shared achievement. There is always someone to move with and someone to catch up to.

Badges mark the milestones in your own progress. Move, explore and connect with others, then find your next goal. You don't always have to break records to have something to be proud of.
An afternoon walk in the park? Walked the last two stops? It counts in GRUNDO too!
Growing your grund, reaching the next level, or simply taking a new detour home.
