Stepwars has not launched yet. It is an independent iOS walking game in which a deliberately started walk uses validated GPS distance for personal territorial progress, missions and a camp, even when no other players are nearby. The website explains the game, its current rules and how location data is handled.
Public App Store distribution has not been announced, and the app cannot be downloaded yet. No pricing or release date is published here. The screenshots are development previews from a simulator, not a recorded real-world walk.

The game is built around a simple goal: give an everyday walk a visible sense of neighborhood exploration and personal progress, including when there are no other players nearby.
