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
Transform the way you visit trade fairs. EastmarkHK Trade Shows captures products, suppliers, booth locations, voice notes, photos, and business cards — all directly from your iPhone or iPad, even with no signal on the show floor. CAPTURE AT THE BOOTH - Quick Capture mode gets a product logged in about 30 seconds — camera, photos, or a scanned business card - Business card scanning with on-device OCR (Vision) reads names, companies, and contact details automatically - Voice notes with live transcription, so you can describe a product without typing while standing at a booth - Notes, category, reference, price, MOQ, tags, and status per product STAYS OUT OF YOUR WAY - 100% offline — no signal required at the venue, no data entered twice back at the office - Organize by trade show (e.g. "Canton Fair 2026"), with companies and linked products - Search and filter everything by status once you're back online AFTER THE FAIR - Export a PDF report with photos for your team or your files, shared via AirDrop, Mail, or Files - Export contacts with a field picker and duplicate detection - Optional sync to iCloud Drive, OneDrive, or Google Drive - Windows companion app available for desktop review and export Built for trade fair professionals — sourcing teams, buyers, and import-export companies — who need a fast, reliable way to capture everything at the booth without depending on a signal or typing everything twice later.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
