Project breakdown

The challenge

Athletes need a distraction-free, customizable interval timer with hands-free voice cues, lock-screen visibility, and post-workout effort tracking, without juggling a manual stopwatch.

Built from the Boostie MVP through to F1T on the App Store, as lead iOS developer at Livita Software:

  • SwiftUI timer engine with sets and cycles

  • Perceived-exertion capture
  • Core Data and CloudKit workout history
  • RevenueCat and Superwall monetization

Results & proof
