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

Lotto Master is the smartest way to pick numbers for Powerball and Mega Millions. Stop using the same numbers everyone else does. Lotto Master generates fresh, never-before-drawn combinations and checks every set you create against the full history of past winning numbers — so you'll never play a combination that's already been picked. KEY FEATURES - Generate Master Combinations One tap creates a fresh set of numbers for Powerball or Mega Millions, drawn from real probability distributions and verified against every past draw. - Check My Numbers Have a favorite combination? Lotto Master tells you instantly if those numbers have ever been drawn before, and if so, when. - Save Your Picks Build a personal library of the combinations you actually want to play. Pull them up at the counter without scrambling. - Always Up to Date Latest drawing results are pulled automatically and cached on your phone, so you can use the app even without a signal. - Two Games, One App Full support for both Powerball and Mega Millions — switch between them with a single tap. - Designed for the Player Clean, fast, and built around what you actually do at the counter or on draw night. No ads. No accounts. No clutter. WHY LOTTO MASTER The lottery is a long shot — that's why people play. But not every combination is the same. Some have already been drawn. Some have unusual quirks. Lotto Master helps you sidestep the already-drawn combinations and play with picks that are statistically just as likely to hit, but haven't shown up yet. It's still gambling. It's still a long shot. But it's smarter. DISCLAIMER Lotto Master is for entertainment and convenience purposes only. It does not guarantee or imply any winnings. Past lottery results do not predict future draws. The app does not facilitate the purchase of lottery tickets — you'll still need to play through your state's official channels. Please play responsibly..

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.
