Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
*** App Store Beste Kinder-App 2013 *** Sprechendes ABC ist ein interaktives Alphabet, das mit viel Liebe und Sorgfalt entwickelt wurde. Hier wird das Lernen von Buchstaben zum aufregenden Unterfangen, da lustige Tiercharaktere im Knetanimationsstil dem Leseerlebnis Spaß einhauchen. Jedes Tier hat einen Sprech-Modus, mit dem ein Kind die unterschiedlichen Buchstaben und Laute nicht nur hört, sondern mit dem außerdem an der eigenen Aussprache gefeilt werden kann.

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.

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.
