Hey Product Hunt 👋 I'm Charles, founder of MonsterFit. The first version of MonsterFit was an AI agent that wrote custom meal and workout plans. It reached 300+ users, and then I noticed something: people didn't quit because their plan was bad. They quit because nobody was watching and nothing was at stake. So I rebuilt it around what actually keeps people training: rivalry, accountability and visible progress. How it works: 🏋️ Challenges. Record your reps in-app, and AI pose detection scores your form and count. No honour system. 🏃 Walk/Run challenges with GPS tracking for steps, pace and cadence. 🏆 Ranks. Climb five tiers, from Recruit to Monster. 🎁 Rewards. Earn points you can redeem with partner brands. We're starting in West Africa, where gym culture is growing fast but most fitness apps weren't built with local users in mind. I'd love your honest feedback, especially on the challenge and ranking mechanics. What would make you come back every day? 💚

What actually keeps you going back to the gym?

Hey everyone I'm Charles, co-founder of MonsterFit.

My co-founder and I are both gym regulars, and we kept seeing the same thing: people start strong, then quietly drop off within a few weeks. Not because they lack a plan, but because nobody's watching and nothing's at stake.

We're building MonsterFit to fix that. You record your workouts in the app, AI verifies your reps and form, and you climb ranks from Recruit to Monster, compete in challenges with friends, and earn rewards from partner brands. Rankings you can't fake.

We launch here on November 9, and before then we'd love your input:
