Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.

States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.

Differentiate and validate

Hypothesis: Contractors need faster repeat invoices more than more templates.

First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.

The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.

Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description

Barcelona Gothic Quarter is SelfTour’s most unique GPS assisted walking tour of one of the world’s most beloved and beautiful cities. Barcelona is a city of art where history is combined with a contemporary, hip vibe. With turn-by turn GPS and voice guided instructions we lead you through Barcelona’s very popular Gothic Quarter’s maze of narrow streets revealing its fascinating history, wonderful shopping, culture and spectacular architecture. Put On Your Headsets And Go! We bring our show biz experience this and each tour to insure it is a fun experience. - A complete circle walk of the Gothic Quarter’s significant sights, from those of the early Roman village then called Barcino, to the Kingdom of Aragon to 19th century Catalunya. - Visit and hear about over 60 fascinating locations, including a walk along one of Europe’s most famous streets, the beautiful La Rambla. Others include the Plaza of Saint Jaume, the Royal Plaza, Gaudi’s Guell Palace, Casa Bruno Cuadros, the spectacular Boqueria Market, the charming Canaletas Fountain, Roman temple columns, the Crown Jewels of Aragon, Liceu Theater, and even where you can explore the earliest ruins under the existing city. And some legends of the city are shared. The tour is great background for a visit to Gaudi’s now famous La Sagrada Familia Basilica. - Your guides are experts who delightfully describe the locations aided by appropriate music and audio effects to dramatically bring alive historical events and characters. - For sports fans, you’ll hear about the famous Barca Futbol (soccer) team and visit their center where you can see a video experience the outrageous excitement of their games. - The descriptions have all been thoroughly researched providing accurate information. Photos of each location verify you are looking at what is being described. ### SelfTour™ is a trademark of SelfTour Audio Adventures

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
