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
POWERBALL WEIGHTED GENERATOR A smarter way to explore Powerball numbers. Powerball Weighted Generator uses historical drawing data, recent trends, and customizable weighting strategies to generate number combinations based on the preferences you choose. SMART WEIGHTING Choose how strongly historical and recent data influence your number selection. Use Historical, Recent, or Smart strategies and adjust weighting strength from Off to High. GENERATE YOUR PLAYS Generate 5, 10, 20, 50, or 100 Powerball combinations at a time. Your generated plays are scored according to the selected weighting strategy. EXPLORE THE DATA Review historical number frequency and see which white balls and Powerballs have appeared most often. TRACK RECENT TRENDS Compare recent drawing activity with current-format historical results to see how number frequencies have changed over time. TEST THE GENERATOR Run batch tests of up to 100,000 generated plays and review selection statistics and filtering results. KEEP DATA CURRENT Refresh the historical drawing database using official Powerball data. BUILT-IN FILTERING The generator automatically avoids previously drawn combinations, combinations containing three or more consecutive white balls, and duplicate generated plays. CURRENT POWERBALL FORMAT The app uses the current 5-from-69 white-ball format and 1-from-26 Powerball format introduced in October 2015. IMPORTANT Powerball drawings are random. This app does not predict winning numbers or increase the mathematical odds of winning. Weighting and trend information are provided for analysis and number-selection preferences only. Powerball Weighted Generator is an independent number-generation and analysis tool and is not affiliated with or endorsed by the official Powerball lottery.

Opportunities
AI-GENERATED OPPORTUNITY HYPOTHESES
These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.
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.

From the Build Kit assessment.
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.
