Brawler: AI boxing coach app, $25,300 MRR
Brawler is an AI boxing coach app that once hit $60,000 in a 30-day window within months of launch, verified at $25,300 MRR in the AI mobile apps category (median $24,600 MRR, $5 per customer). The interesting pattern is an AI coach for one narrow sport — close to physical coaching work — though the $60k figure was a spike, not steady revenue, and boxing is a narrow niche.
