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
Cards and savings at your fingertips This app does one thing: store and show your loyalty, discount, and rewards cards—fast, with zero clutter. • Truly simple: open → find a card → show the barcode. • No ads and no “storefronts” — just your cards. • No sign‑up required. Use it right away. Want to keep access when you switch devices? Sign in with Apple. 1) All your cards in one place Keep discount cards and loyalty cards together so you can find the right one in seconds and never miss a deal. 2) Bulk import from screenshots Moving from Stocard or another app? Upload screenshots and your cards appear neatly—no re‑adding them one by one. 3) Add to Apple Wallet — clean and customizable Export to Apple Wallet with a handy editor, so each card looks the way you want. 4) Geo recommendations (beta) When you’re near a store, the app can suggest the cards you’ll likely need at checkout. 5) AI assistant for quick adding Snap the barcode side—AI identifies the card name, finds a logo, and speeds up adding. You can use the app for free, or upgrade to Plus or Pro. Payment for the Plus or Pro plan will be charged to your iTunes account at confirmation of purchase. Subscription automatically renews unless auto‑renew is turned off at least 24 hours before the end of the current period. You can easily manage your subscription in your account settings.

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.
