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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Do you know if you can retire early? Do you know if your current savings plans are enough? Do you need to put more money into your 401k each year? This Easy Retirement Calculator keeps it simple for easy high-level planning and comparing different scenarios. (How much more would you have at retirement if you increase your savings, or if your investments make higher interest?) This application is about giving you the tools you need to estimate your retirement years. The calculator lists the assumptions on the front page, and lets you pick your own options This retirement calculator takes inflation fully into account. Many similar calculators ignore inflation, which is a grave mistake. Even assuming a modest inflation rate of 3%, $100 today will only have the purchasing power of $55, 20 years from now. It is extremely important to take inflation into account when planning for retirement. This app lets you make all the decisions: Choose your current age and age of planned retirement Choose the rate of inflation (defaulted to the standard 3%) Choose the rate of return on your investments. You are able to calculate different rates of return on different investments, if desired. Choose your current Savings and 401k balances Choose how much you plan to add to your savings accounts each year. This will be automatically indexed to the rate of inflation. Choose your life expectancy age or "end of retirement" date to see how much you would be able to spend each year of retirement OR Choose the spending amount you need to maintain your desired standard of living, and see how many years your nest egg would last. This application lets YOU make the choices regarding inflation and rate of return / interest rate. A small change in these rates can have a drastic effect on projected income. With this app, YOU get to make that choice. All rates are defaulted at startup to fairly standard rates. Save your various retirement scenarios for later retrieval, and to compare against each other. This application is Ad-free. It does not try to sell you financial services, or attempt to persuade you to invest in any particular stocks or bonds. Disclaimer: This application is a calculator using your assumptions and input. It does not provide financial advice. Please contact a licensed financial planner for specific retirement advice.

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.
