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

You already give your kids allowance. KidCash keeps the books. No debit card. No bank app. No kid login. KidCash is a private, beautifully designed ledger for the Bank of Mom and Dad. Set allowance to pay itself, add real interest, and turn “I’ll pay you back” into balances your kids can actually watch grow. ALLOWANCE ON AUTOPILOT Set the amount and schedule it daily, weekly, biweekly, or monthly. KidCash pays allowance automatically, even when the app is closed. Pause anytime or skip a single payment without losing your setup. Get notified every time allowance lands. INTEREST THAT TEACHES COMPOUNDING Give each child a savings rate and let them experience how money grows over time. Choose simple or compound interest, set minimum balance requirements, and cap how much earns interest. Preview the exact next payout before it happens. SAVINGS GOALS THEY CAN SEE Create goals for a bike, game console, shoes, or anything else. Watch the progress ring fill as balances grow. “Amount Remaining” keeps goals clear and motivating, and completed goals stay marked as Reached. PAY EVERYONE AT ONCE Deposit the same amount to every child or split a total evenly between them. Leftover pennies are distributed fairly, and you can preview every amount before confirming. EVERY DOLLAR ACCOUNTED FOR Add or remove money in seconds with quick amount shortcuts and reusable notes. Undo mistakes with a tap. Edit or delete any transaction and balances automatically recalculate. Search full history, filter by transaction type, and jump across years instantly. SEE WHERE IT WENT The Insights tab shows monthly and lifetime totals, tracks active kids, and breaks down deposits, withdrawals, allowance, and interest at a glance. Each child also gets their own balance history chart. PRIVATE BY DESIGN Protect the app with Face ID, Touch ID, or your device passcode. Balances automatically hide in the app switcher so sensitive information stays private. YOURS ON EVERY DEVICE Sync securely through iCloud across iPhone and iPad. Export statements for one child or the whole family as CSV or PDF files with running balances, ready for Files, Mail, or printing. BUILT FOR REAL FAMILIES Years of history stay fast and responsive. Currency automatically matches your region. Your data stays yours. No accounts to create, nothing sold, and nothing shared. Give allowance the same way you always have. Just never lose track of it again.

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.
