Rep Track
I wanted to get my hands dirty with AI tooling and see what was actually possible. So I picked a real problem: every gym app I'd tried wanted a subscription for basic tracking.
Claude and I wrote the whole thing in a day. 17 Swift files. SwiftData models, a pattern recognition engine, 80+ exercises, haptics, PR tracking.
It wasn't good yet. But it ran. And I could log a workout with it the next morning.
