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

The RV Loan Payment Calculator PRO turns you into a master negotiator when shopping for an RV by quickly and easily calculating a monthly loan payment or an affordable purchase price on location with your mobile device. Works on any motor vehicle that can be financed, including all types of RVs and boats. Users can save multiple RV loan scenarios. You can save 7 different scenarios per calculation screen for a total of 21 scenarios. Exporting of the RV Loan Data: You can export the data and then send it via a Text message or an email message. Just press the Export Data button and the app will ask if you want to send it via email or text. You then press the email or text button and the app will paste all of the data into the body of the message. No Ads on this version. SAFE - We DO NOT collect any personal information with this app. At the start screen, you simply choose what you want to calculate: 1. Monthly, biweekly, and weekly Loan Payment if buying from a Dealer. 2. Monthly, biweekly, and weekly Loan Payment if buying from an Individual. 3. The Price of an RV that you can afford based on the monthly payment of your choice. You then simply enter the required information (e.g., price, interest rate, term of loan), plus any optional information (e.g., trade-in, sales tax rate, rebate, loan payoff, etc.), and then press the calculate button. Unlike the free version, this one allows you to export the numbers that you have entered and does not show any ads. 3 main options are available to the user on the start screen: 1. Calculate a Monthly Loan Payment if buying from a Dealer. This option offers allows the user to input all items that a dealer finance manager would input into their system to calculate a monthly loan payment. Users can enter: 1. Price of RV (required) 2. Trade-In Value (optional) 3. Instant Cash Rebate (optional) 4. Down Payment (optional) 5. Dealer Fees (optional) 6. Miscellaneous - extended warranty, dealer add-ons, etc. (optional) 7. Sales Tax Rate (optional) 8. Interest Rate (required) 9. Loan Payoff (optional) 10. Term of Loan in months (required) 11. Annual Expenses (optional) - you can also press a button to enter itemized expenses if you need help determining the total annual amount. 12. Extra Payment (optional) You can also select whether to apply sales tax to the trade-in and/or rebate. You may also choose whether to finance the total sales tax (i.e., include it in the loan). The app then calculates the monthly loan payment of the RV based on the information above. It will also display the total amount financed and the total sales tax. 2. Calculate a Monthly Loan Payment if buying from an Individual. This is the simplified version. Users can enter: 1. Price of RV (required) 2. Down Payment (optional) 3. Sales Tax Rate (optional) - used only for informational purposes. 4. Interest Rate (required) 5. Term of Loan in months (required) 6. Annual Expenses (optional) 7. Extra Payment (optional) The app then calculates the monthly loan payment of the RV based on the information above. 3. Calculate the Affordable Purchase Price of an RV based on the monthly loan payment interest rate, term of loan, and any other optional information. Users can enter: 1. Monthly Payment of RV (required) 2. Trade-In Value (optional) 3. Down Payment (optional) 4. Dealer Fees (optional) 5. Miscellaneous - extended warranty, dealer add-ons, etc. (optional) 6. Sales Tax Rate (optional) 7. Interest Rate (required) 8. Loan Payoff (optional) 9. Term of Loan in months (required) You can also select whether to apply sales tax to the trade-in. You may also choose whether to finance the total sales tax (i.e., include it in the loan). The app then calculates the affordable purchase price of the RV based on the information above. It will also display the total amount financed and the total sales tax.

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.
