Grit Saga turns your real workouts into an RPG. Scan your body and get a pixel-art avatar that levels up as you actually get stronger. Skip training, and a "boss" shaped like a bad habit (Couch Potato, Snack Warlock, Screen Zombie) shows up — you can only beat it with real reps. Duel friends over 7-day XP races, track food/training/recovery in one place, and get AI coaching that knows your actual history. Built solo, no team, no funding.
