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.

Stop guessing. 1 cup of flour is NOT 1 cup of sugar. Generic converters treat every ingredient the same. They don't. A cup of all-purpose flour weighs 125g. A cup of granulated sugar weighs 200g. A cup of butter weighs 227g. Get it wrong, and your recipe fails. BakeWeigh knows the density of every ingredient. Just pick what you're measuring, enter a quantity, and get an accurate conversion — every single time. ACCURATE INGREDIENT CONVERSIONS • Density-based conversions for 55+ baking ingredients • Cups, tablespoons, teaspoons, ounces, grams, milliliters, and more • Covers flour, sugar, butter, cocoa, honey, nuts, leaveners, and beyond • No generic "1 cup = 240ml" shortcuts — real weights for real ingredients RECIPE SCALING • Scale any recipe up or down instantly • Double a batch, halve a recipe, or convert for any serving size • Maintains proper ratios across all ingredients TEMPERATURE CONVERSION • Fahrenheit, Celsius, and Gas Mark • Quick reference for common baking temperatures WORKS OFFLINE • No internet connection required — ever • All conversions happen on your device instantly • Zero data collected. Your recipes stay yours. FREE TO USE • 15 common ingredients included free • Basic volume, weight, and temperature conversions • No ads, no tracking, no account required UNLOCK PRO — ONE-TIME PURCHASE • 55+ ingredients with precise density data • Unlimited conversions and recipe scaling • All future ingredient additions included • Just $3.99 — pay once, own it forever Built by a baker who got tired of wrong conversions. Designed for home bakers, pastry chefs, and anyone who takes their recipes seriously. No subscriptions. No ads. Just baking.

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.
