Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
EASY AND SIMPLE REGISTRATION We are lowering the barrier of entry for individuals of any age and income bracket to start their investing journey. With just your NIN and contact details, you can join Bamboo and start trading with zero paperwork right from your mobile phone. INSTANT TRADING Whether you want to invest in companies you believe in and hold, or you wish to frequently liquidate your position to take advantage of the ups and downs of the market, you can begin realizing your dreams and profits. SECURED TRADING Bamboo protects you by ensuring all your trades and positions are insured by the SIPC and FINRA up to $500,000. You can freely buy and sell US stocks knowing that your money is safe. UNPRECEDENTED ACCESS Non-US citizens have had severely limited access and high barriers of entry to the US stock market. Bamboo is providing an incredible opportunity to invest in over 3,000 stocks, with a market capitalization of over 21 trillion USD. FRACTIONAL INVESTING You can start investing with as little as N15,000 in any company you desire. Our partnerships enable Bamboo users to own fractions of shares in different companies thereby giving users even more options to trade the stocks they desire. EARN, EARN, EARN! The US stock market is one of the most exciting and definitely the largest stock exchange market in the world. With over 3.6 billion shares traded daily, there are infinite opportunities for you to make a fortune while buying or selling from a variety of stocks. Disclosure: All investments involve risk and the past performance of a security or other financial product does not guarantee future results or returns. You can always lose money when you invest in securities or other financial products. Investors should consider their investment objectives and risks carefully before investing. Bamboo does not provide investment advice and individual investors should make their own decisions or seek independent advice. The value of investments can go up as well as down and you may receive back less than your original investment.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
