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.

Ship Finder shows live moving ships on a worldwide map. The intuitive design combined with incredible performance puts you in control. Watch in full screen, view in AR, search, add filters and so much more! Ship Finder has been top rated and top ranking since 2009 and covers most of the world, tracking 20,000+ ships simultaneously. Our incredible app performance means that you can see all tracked vessels at once - no clustering here! Simply tap a ship to see its name, type, photos, speed, dimensions and much more. Powerful features such as filters, search and the ability to save favourite ships are included. (You can choose Apple or Google maps too!). Add and browse bookmarks to saved locations around the globe to quickly navigate to areas or ports of interest. You can even use Augmented Reality (AR) view to identify ships out at sea using your device camera. Ship Finder works by picking up AIS ship feeds used by all passenger vessels, vessels over 300 tons and increasingly by smaller pleasure craft and yachts. This technology is actually faster than radar and is used by vessels for safety and navigation. Ship Finder provides near real time “virtual radar” AIS maps. It’s easy to use and is an amazing app for anyone interested in shipping, cruising and sailing in ports and locations across the world. It’s also great if you simply want to know what boats are out there or want to see where your friends and family are. Ship Finder is also used extensively by maritime professionals and mariners. Our global AIS coverage is impressive and expanding all of the time as we add new AIS feeds and receivers. Please check www.shipfinder.co regularly to see the latest coverage. Pinkfroot are committed to customer service and continually improve our Ship Finder apps based on feedback.

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.
