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.

Starting solids is exciting - and a little nerve-wracking. Which foods has your baby tried? How many times, and did any of them cause a reaction? Baby Food & Allergy Tracker keeps it all in one calm, simple place, so you can introduce new foods with confidence and catch reactions early. It's built around the common-sense approach many pediatricians recommend: offer a variety of first foods - including common allergens like peanut and egg - one at a time, and keep an eye out for any reaction. WHAT YOU CAN DO - Track 104 first foods, sorted by group: veggies, fruits, protein, grains, fats, and herbs & spices - covering all nine major allergens - Log every try, not just the first - each one keeps its own date, reaction, and note - Set or correct the date on any try, so it matches when you actually fed it - Record the reaction: none, a reaction, or not sure - so you can spot patterns - Add your own foods, for family recipes and anything that isn't on the list - See each baby's progress at a glance: how many foods tried, and how they went - Search and filter by food group, tried status, or reaction FOR EVERY LITTLE ONE Track each of your children separately - each with their own food list, history, and notes. PRIVATE BY DESIGN No account, no sign-up, no cloud. Everything stays on your phone. Pay once, use forever. WHY IT HELPS When your pediatrician asks "has she had egg? how many times? any reaction?", you'll have a clear answer instead of trying to remember. A simple record makes the whole first-year food journey less stressful - and gives you something concrete to bring to check-ups. Baby Food & Allergy Tracker is a personal tracking tool, not medical advice. Always follow your pediatrician's guidance on introducing solids and allergens, and seek medical help right away if your baby has a serious reaction. Start tracking your baby's first foods today.

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.
