Case Study

A workout app where every rep levels you up.

A fitness app for people who stick with games longer than gym routines. Every major muscle group gets its own rating, and every logged workout pushes it forward — so getting stronger feels like progress you can actually see, not just a number on a plate.

The challenge

Most fitness apps track workouts as raw numbers — sets, reps, weight on the bar — none of which feels like progress day to day. A founder wanted training to feel like a game: visible levels, visible growth, a reason to open the app beyond guilt.

What we built

A gamified strength-training tracker for mobile that rates and levels up every major muscle group as you train.

  • A per-muscle rating and leveling system — each major muscle group is tracked and leveled independently, so you can see exactly what's improving and what's lagging
  • Workout logging that feeds directly into muscle levels — every set and session moves the needle
  • Visual progress screens showing level-ups muscle by muscle, not just a single overall score
  • Cross-platform from one codebase, shipped to both iOS and Android
  • Push notifications for workout reminders and streaks

After we shipped it, the app secured funding — validation that turning strength training into a leveling system wasn't just a fun idea, it was one people wanted to keep training with.

One React Native codebase ships to both iOS and Android. Supabase handles authentication and data, with row-level security so each user's workout history and muscle ratings stay private and tied to their own account.

The outcome

A fitness app that made "did I get stronger this week" a visible, game-like answer instead of a guess — and one the founder was able to secure funding for after we shipped it.
