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
World news, rated by significance. Newsworthy assesses the significance of world news. Each reading has a score from 1 to 10, a brief explanation and an update time. Higher scores mean more consequential developments. The displayed score fades as developments age. THE PAST WEEK, IN ONE LIST Below the reading, the past week's developments: one entry for each, in the order Newsworthy first covered it, with its story and how long ago it broke. The list ends at one week, and Settings can hide it. STORY AND AGE Under the sentence, a quieter line first says when Newsworthy last checked the news, then names the story and how long ago it was first reported, such as "US Iran War · 5h ago". Tap the line to switch between the two. For two hours after Newsworthy begins covering a development, its sentence starts with a bold "New:". HOME SCREEN WIDGETS Small and medium widgets show the reading and when it was last checked. Each widget has its own settings: show or hide the app name, and choose Follow device, Light or Dark. Widget refresh timing is controlled by your device. NOTIFICATIONS AT YOUR CHOSEN SCORE Choose the minimum score you want to hear about in Settings. Notifications are off by default; when enabled, the initial minimum is 8. Receive a notification when the displayed reading meets your choice, without repeated alerts for routine updates to the same development. Tap a notification to open the current reading. Notifications depend on connectivity and your device settings and are not an emergency service. YOUR APPEARANCE AND SAVED READING Choose Follow device, Light or Dark in Settings. After an online launch, the last downloaded reading stays available offline with its original timestamp. Share the reading using your device's share sheet. Privacy and Support are in Settings. ONE-TIME PURCHASE The download purchase helps offset the cost of running the service. No subscription, in-app purchases or ads. No account or login is required. Ratings can be wrong. Newsworthy provides general news context, not a complete briefing, an emergency alert or a measure of personal safety. Readings update periodically and saved readings may be outdated. Check the displayed update time.

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.

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.
