Make every move count.
GRUNDO turns your runs, walks and bike rides into a game played across your city. Close a loop to claim the territory inside it, defend your grund and take over cells from other players.
CLAIM YOUR CITY
The map is divided into hexagonal cells. Your route decides what you capture — every outing can change the map.
TRACK YOUR ACTIVITY
Record your route, distance, time, pace or speed. Review your activities, splits and personal bests, and see the territory and GP you earned.
FIND YOUR NEXT MOVE
Plan a route, explore missions or ask Geri, the optional route assistant, for ideas. Try a new loop or head toward a rival’s territory.
PLAY TOGETHER
Follow friends, share activities, compare leaderboards and join a crew. Like and comment on activities, chat with your crew and keep an eye on your rivals.
YOUR LANGUAGE, YOUR UNITS
Use GRUNDO in English or Hungarian. Choose metric or imperial units for distance, pace, speed and elevation. Territory is always shown in square kilometers.
Location access is needed to record activities, including while the screen is locked. You control when recording starts and stops. GRUNDO is for users aged 16 and over.
Ratings & Reviews

• New crew leaderboard: tap the trophy in the Crews header — your crew members' combined territory, with Walk/Run and Bike separately, in daily, weekly, monthly and all-time views.
• The leaderboard now shows everyone: it loads 20 at a time, with a "Load more" button.
• Crew management: founders can rename their crew, edit its description and city, switch between public and private, replace the invite code, or disband the crew; a removed member can also be banned.
• Mistyped your email? You can request the code to a different address right from the verification dialog.
• Two-letter initials for profiles and crews without a picture; long names now fit on the podium.
• Many smaller fixes.
