Generating… usually about a minute.
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.

Shoppalist is a clean, no-nonsense shopping list built for the way you actually shop — iPhone in your pocket, Apple Watch on your wrist. MULTIPLE LISTS Create up to five color-coded lists and swipe between them. Weekly groceries, a party run, a hardware store trip — each list has its own name and background color so you can tell them apart at a glance. APPLE WATCH COMPANION Everything syncs to your wrist the moment you add it. The Watch app lets you check items off directly from your Apple Watch, and a complication on your watch face always shows how many items are still outstanding. SIRI SHORTCUTS Just say "Add milk to Shoppalist" and it's done — no need to unlock your phone or open the app. Shoppalist's Siri integration handles quantities too, so "Add three avocados to Shoppalist" works exactly as you'd expect. SMART SUGGESTIONS Shoppalist remembers everything you've ever added. As you type, it offers quick-tap suggestions so your regular favorites are only one tap away. QUANTITIES & EDITING Set exact quantities with the built-in stepper when you add an item. CHECK OFF WITH UNDO Tap an item to check it off — it disappears after a short delay so your list stays tidy. Changed your mind? An undo bar catches you before it's gone for good. Swipe to delete instantly, or undo that too. SHARE YOUR LIST Send your shopping list to anyone via iMessage or the system share sheet with a single tap. Only unchecked items are included, so what you share is always current. COMPLETELY PRIVATE All data lives on your device and syncs privately via iCloud. No account required. No ads. No analytics. No third-party SDKs. Nothing leaves your devices except through Apple's own iCloud — ever. BARCODE SCANNER Quickly scan barcodes to add items to your shopping list. It’s an easy way to check what you already have at home and keep track of what you need while doing a fast inventory scan.

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.
