Free · Fitness App PRD Starter

Free, from a 10-year studio operator: the 15-minute spec that turns your fitness app idea into something Claude Code or Lovable can actually build.

One finished client-intake spec, the prompt that writes yours, and a 5-day email course from idea to live app. No code needed.

What you get

prd-client-intake.md      a finished spec: one form, one table, one list.
                          Buildable in an evening. Deliberately no health questions.
the-15-minute-prompt.md   an interview your AI runs on you. Answer it,
                          and it writes a spec in the same shape for your app idea.

The 5 days

1. 01 The one-page idea that survives contact with an AI
2. 02 Why your app needs a spec before it needs a prompt
3. 03 The three apps almost every fitness business could use
4. 04 What breaks after the first prompt, and why nobody warns you
5. 05 From spec to something a client can open on their phone

Why a spec first

The AI built your app in four minutes. Then it broke at prompt two. The fix isn't a better prompt. It's a document written before the first prompt, and this is your first one, free.

Ex-pro athlete. 10 years running boutique fitness studios (UAE + US), multi-unit exit. Now shipping fitness apps with AI from Costa Rica, no code, and handing you the specs and prompts to do the same.
