Stomp City

Stomp City records your movement across London, showing you what percentage of the city you’ve covered. As you walk, streets you’ve been down turn green on the map, letting you slowly “complete” London like a real-world exploration game. You can also track progress by borough, and take on fun challenges - like seeing which of London's Blue Plaques you've walked past, or what % of One Word Roads you've completed. Stomp runs in the background (if you allow it), and all your data stays stored locally on your phone.
