FitForge

FitForge is a personalized fitness app that creates adaptive workout plans and automatically adjusts your training based on real performance data. Instead of following static routines, the app learns from every logged set—intelligently programming weight, reps, and volume to keep you progressing toward your goals without manual planning. Target users are fitness-minded adults aged 20–45 who want structured, effective workouts without hiring a personal trainer.

The business operates on a freemium model: a free tier offers basic workout plans and manual logging, while Premium ($9.99/month or $59.99/year) unlocks AI-driven adaptive plans, advanced metrics, nutrition tracking, and program customization. Success metrics include monthly active users, free-to-paid conversion rates, subscriber churn, and weekly workout frequency per active user.
