Plaicise was a clever camera-based movement app that turned basic bodyweight exercises like squats, jumping jacks, and side-steps into quick arcade games. Kids stood in front of their phone or tablet camera and used their body to slice virtual targets or dodge obstacles.

The catch? You cannot get it anymore. In 2024, the German developer repurposed the app store listing into a local city-guide app called plaYce, pulling the fitness games entirely off the store. If you are looking for a active camera-tracked fitness game that actually exists today, look at Active Arcade instead.
