Pushup RPG: Fitness Quest

Pushup RPG is a free iOS and Android game that uses on-device camera pose detection to count your reps in real time as you fight monsters and progress through an RPG. You prop up your phone, do pushups or squats, and every rep deals damage to enemies across eight biomes with forty-eight hand-crafted foes. The game features loot, gear upgrades, skill trees, live duels against friends, and leaderboards, with all pose detection happening on your device and camera video never uploaded.
