TrainWiz

Most fitness apps feel like a spreadsheet with guilt attached, so people quit by week two. TrainWiz makes it a game you actually want to open. Prop up your phone, do real bodyweight exercises like squats or push-ups, and on-device AI counts every rep (no video ever leaves your device). Those reps power a real RPG: battle through 100+ stages, catch and raise 100+ monsters, and evolve your team. Plus live co-op, train with a friend in real time. No gym, no equipment. Free on iOS & Android.
