Walkr - A Gamified Fitness App is a space-themed adventure game in which players earn energy points for their spaceship by walking in real life. Steps are recorded via the player's phone pedometer, and they show up in the game as available points to use to fuel the spaceship. A little alien gives instructions via text-like bubbles. It's not a game that's played and completed in a few sessions: There are more than 30 missions, 25 planets, dozens of creatures, and upgraded spaceships for players to acquire. Exploration and spaceship upgrades require steps and time, and some missions require teams formed with other people on social media also using the app.
