What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

THE PREMIER IPAD ATLAS - with RETINA VECTOR MAPS The World HD is unique in the app store because it includes both a complete set of country maps AND the largest world fact book. These enable it to answer questions which Atlases and fact books cannot: Atlases show you where countries are located, but have very little information about them; fact books tell you about each country, but their maps leave you guessing about where places are located. ___________ HOW IT WORKS ___________ The interface is animated and interactive. Touch a country on the world map and the Retina vector country map opens while the factbook slides onto the screen, each topic neatly organized as tiles along the edge of the map. Touch a factbook tile and it zooms out to reveal detailed information about that topic. Not sure where a country is located? Select it on the drop-down list and The World HD zooms in on it then opens the map and factbook. The zoomable world map is not just the fastest way to select a country it also enables you to visualize and understand entire regions. It is so intuitive and easy to explore that once you get started it's hard to stop! ___________ FEATURES ___________ RETINA VECTOR MAPS ** Includes high-resolution Retina vector maps for EVERY COUNTRY built-in! Unlike the other atlases, these maps remain in focus at all magnifications so you can easily see even the smallest detail. These aren't the CIA maps found in the factbooks, they are used in printed atlases. MORE INFORMATION ** Contains geopolitical and demographic information on 300 countries and regions. NO INTERNET CONNECTION is required ** Except for live Wikipedia content, all data and maps are built-in INNOVATIVE FACT BOOK PANEL ** Presents each section of the fact book as tiles enabling you to quickly find what you need, while keeping the country map in view. HIGHLY ANIMATED INTERFACE ** Responds to your touches and gestures so you can quickly find the information you are looking for. CIA WORLD FACTBOOK ** This trusted source of current country information is built-in for every country, including sections on: introduction, geography, people, economy, communications, transportation, military, and transnational issues. WIKIPEDIA ** View the live, community-written Wikipedia content for each country, island, and remote region within the app. SHOWS YOU where countries are located ** Not sure where a country is located? Select it on the country list and The World zooms to it on the world map and opens the Fact Book Panel DESIGNED FOR YOUR IPAD & IPHONE ** Thoughtfully uses the whole screen to present maps and data

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
