Guided Journey · Create × App

Create an App

Idea → validated, well-architected app

Takes you from a raw app idea to a validated, cleanly architected first version that ships on a sustainable cadence. It orchestrates its ten skills phase by phase, asking you the decision questions at every step and recording every result in your project's docs/ folder so the journey resumes across sessions.

Written to your repo
  • docs/PRODUCT.md
  • docs/EXPERIMENTS.md
  • docs/DESIGN.md
  • docs/ARCHITECTURE.md
  • docs/TESTING.md
  • docs/TECH-DEBT.md
  • docs/STRATEGY.md
  • docs/CREATE-APP-PLAN.md journey tracker — stop anytime, resume any session

One prompt runs it

Every phase asks before it acts, and every decision lands in your project’s docs/ folder as a living document — quit anytime, resume in any session.

Use it when you need to
  • Start a new app without betting months on an unvalidated idea
  • Sequence validation, architecture, and domain modeling correctly
  • Keep the codebase clean and honestly sized from day one
  • Ship on an appetite-bounded cadence instead of an endless roadmap
  • Decide which scaling techniques you do NOT need yet

Journey Map

10 phases, one deliberate order

Each phase invokes one skill from the library, asks you the decision question, and writes the answer to your project’s docs/ before moving on.

  1. 01 Is the riskiest assumption true, and what is the MVP? Lean Startup lean-startup → docs/PRODUCT.md + docs/EXPERIMENTS.md
  2. 02 What should the core flow be? Design Sprint design-sprint → docs/DESIGN.md + docs/EXPERIMENTS.md
  3. 03 What boundaries keep options open? Clean Architecture clean-architecture → docs/ARCHITECTURE.md
  4. 04 What does the code mean? Domain-Driven Design domain-driven-design → docs/ARCHITECTURE.md
  5. 05 Is each function readable and tested? Clean Code clean-code → docs/TESTING.md
  6. 06 Which habits keep it healthy? Pragmatic Programmer pragmatic-programmer → docs/TESTING.md + docs/TECH-DEBT.md
  7. 07 How big must it really be? System Design system-design → docs/ARCHITECTURE.md
  8. 08 Does it feel native on iOS? iOS HIG Design ios-hig-design → docs/DESIGN.md
  9. 09 What ships, and what is cut? The 37signals Way 37signals-way → docs/PRODUCT.md + docs/STRATEGY.md
  10. 10 Where is complexity hiding? Software Design software-design-philosophy → docs/TECH-DEBT.md + docs/ARCHITECTURE.md
In Practice

Start an App with Validation AND Sound Architecture

You want to move fast, but not by mortgaging the codebase in week one.

New app: [describe]. Take me through the create-app journey —
validate the riskiest assumption first, then make the
expensive-to-reverse architecture decisions deliberately,
and record everything in docs/.

Use create-app skill.
