Week 17: Our Founding Cohort is Here!

The doors on the 4-Week Fitness App Challenge closed Sunday night, and the founding cohort is in. Kickoff is this week.

The founding cohort is in

• Labs and the community are coming together. The Labs builders are likely joining the free Athlete AI Community, so expect a wave of new people who are building apps.
• Launch learnings are coming. What worked, what didn't and what I'd do differently, shared this week.

What we built last week

• SparkyFitness review: set up and tested, with an honest take.
• How to build your own fitness app: the step by step guide, from idea to an app on your phone.
• REA: reverse engineer any app with Claude: point it at an app you love and see how it's built.
• Anatomy: REA shows how software is built, Anatomy shows how hardware is built. Claude draws your gear as a real machine you can take apart piece by piece, so you can see what is inside a GPS watch, power meter or super shoes and what each part does.
• Post 100 of the 100 day Athlete AI series: a thank you to the community.
• 3 pieces of marriage advice: build your roots where you are, it's okay to not be in sync, and ask questions before arguing.
• 7 steps I took to save my NYC Marathon block: from an ITB flare to pain free with two weeks to go.

Coming this week

• The first weekly community call. The vote was unanimous. Bring questions, trade ideas and meet other athletes building with AI.
• Launch learnings: what worked, what didn't and what I'd change.

Community notes

• Growth: 1,226 members, up from 1,202.
• Didn't get into Labs? Come be a tester: a group of members is forming to demo and beta test the first apps the Challenge builders ship.
