Bri5k, from couch to App Store

A couch-to-5K iOS app with Apple Watch support. Designed, built, and shipped to the App Store

2025bri5k.com ↗

A 9-week program of walk-run intervals that takes you from zero to running 5K, with an Apple Watch app alongside. I designed and built it from scratch.

A friend wanted to get into running, but every decent couch-to-5K app was locked behind a paywall or a subscription. I also wanted to know how far I could get building a complete product with AI alone.

  • No Figma. The app, the Watch app and the website were all designed and built in Cursor.
  • No design tool for the store either. The App Store screenshots came from a generator built into the website, in developer mode.
  • Through App Review. I used Cursor for the submission too: the questionnaire, the metadata and the review feedback.
