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.

every morning your cat hands you one gold coin. it is yours to spend, no questions asked. go over and the cat is sad, never mad. that is the whole idea behind pennywhiskers. once a month you tell your cat what part of your money is just for you: your fun money, your allowance for little treats. it splits that into days, and each morning there is a fresh coin waiting on the meadow. spend through the day and tap the pixel bills in your wallet as you go. stay above zero and your cat purrs, hearts fill, and a little streak grows. and on the days you go over? nothing flashes red. your cat just looks a bit sad and asks what happened. a treat, a need, an emergency, or you simply forgot to log. you pick, you get one kind line back, and the debt dissolves overnight. a rough day chips a heart and rests your streak, and that is the whole of it. tomorrow's coin is always whole. there is no hole to climb out of and no lecture waiting. just a cat who is glad you came back. life pulls you away sometimes. miss a few days and the calendar simply waits with your cat. fill each one in with a single kind card, say what you spent or that you spent nothing, and the day's coin still comes back. showing up is what earns it, even late. it is a ritual, not a spreadsheet. thirty seconds with your coffee, a purr, and you are done. what living with a money cat looks like one gold coin every morning, your share of the month log a spend in one tap, with pixel bills that add up to what you spent a home screen widget that hands you the coin and takes your bills without opening the app streaks, five hearts, spending charts, and a little month calendar so you can watch the good days pile up gentle reminders written in your cat's own words, only if you ask two very good cats to choose from, a warm ginger and a soft gray with green eyes a pixel meadow that lives through dawn, day, dusk, and night, with rain and snow when the weather turns soft theme music, nature sounds, purrs, and meows, all optional six currencies what pennywhiskers never does link a bank or ask for a login make you an account or ask for an email run analytics, ads, or a server lecture you, or wake you with red alerts your money story lives in one save file on your phone. export it or erase it any time from settings, and deleting the app deletes it. that is the whole deal. pay once. no subscription, nothing to unlock later, no ads. made for cash envelope people, no spend streak people, anyone who says they are bad with money, and anyone who has ever felt bad about a little treat. a kind daily ritual instead of a spreadsheet, one gold coin at a time.

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.
Not assessed in a Build Kit yet.
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.
