Launch
FoxFit is on the App Store. Two people, one AI, and a few months of focused work. Here's what we shipped and what we'd do differently.
FoxFit has been on the App Store for a few weeks now. This is the last post in the series.
What We Shipped
- iPhone app with workout tracking, exercise library, rest timers
- iPad app with the same features, adapted for larger screens
- Apple Watch app for hands-free workout logging
- Mac app for reviewing history and reports
- CloudKit sync across all devices
- HealthKit integration for calories and heart rate
- A set of curated exercises with videos and muscle diagrams
- Achievement system
- Weekly progress reports
Two of us. One AI. A few months.
What We’d Do Differently
CLAUDE.md grew organically until it was a 1,300-line mess and we had to refactor it down. If we’d started with a tight structure we’d have saved weeks. The same goes for PRDs; we wrote them religiously for the big features and skipped them for the small ones, and the small ones had more bugs. The discipline isn’t optional, even when the work feels too small to bother.
The other lesson, which took longer to internalise, was that the first version is almost never right. The third usually is. We learned to ask Claude “is this your best work?” before accepting anything, and a surprising amount of the time the answer was no, so we’d ask it to try again, and it would.
FoxFit is available on the App Store for iPhone, iPad, Apple Watch, and Mac.
