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.

What's on the menu today? With diabetes, that question quickly becomes the day's biggest. «Carb Counter» brings variety back to your plate. Thousands of foods with carb-serving values, one tap is enough. The American Diabetes Association recommends carb counting as an effective tool for managing blood glucose levels — for type 1 and type 2 alike. ≡ ONE TAP IS ALL IT TAKES ≡ Tap on a food, and you see carb-serving values for every portion size. The slider replaces mental math. Save your usual quantities once — the next snack goes even quicker. ≡ COLORFUL MEAL PLANS ≡ Eating isn't just necessity, it's pleasure. With sorting and filters, you find exactly what fits: fewer servings for your insulin budget, just the right amount for intense days. Calories are shown alongside — so you discover alternatives to the same old routines. Three ways to see your food differently: ● Sort — by carb amount, category, or brand ● Filter — set targets, get matching suggestions ● Explore — adjust portion size smoothly, values recalculate live ≡ FLEXIBLE FOR EVERY CARB SYSTEM ≡ Whether you count carb servings (15 g, ADA standard), carb units (10 g, European), or bread units (12 g) — «Carb Counter» switches between them on the fly. One definition at a time, your choice. ≡ MADE FOR EVERYDAY ≡ «Carb Counter» runs offline, on iPhone and iPad. While shopping, cooking, or eating out — the app's there. ≡ INCLUDES ≡ • Carb-serving and calorie values for thousands of foods • Configurable factor: 15 g (carb serving / ADA), 10 g (carb unit), or 12 g (bread unit) • Quick search and full-text search • Sort by carb amount, category, or brand • Slider for portion sizes • Add your own foods anytime • Fully offline and VoiceOver-compatible

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.
