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
Unlimited News is a private RSS and Atom reader for iPhone, iPad, and Mac. Front Page is the paper: the sources you chose, laid out as Headlines or as a Feed, ready offline. FRONT PAGE - Headlines — a clustered newspaper of the day's stories, with your folders as sections - Feed — a list of articles and a two-column reader - Today, This Week, This Month, or All Time - Unread, All Articles, or Starred (Unread is the default) - The same story from several of your sources, grouped once - A catalog of newspapers and magazines to start from, or paste any site, feed, or YouTube channel READING - Open the feed's text, the live page, or a stripped reader - Type you can live with — size and face, light, dark, or the system - Listen to an article, or export it as Markdown - Images and embeds stay blocked until you load them - Search everything already on the device YOUR SUBSCRIPTIONS - Folders are newspaper sections - OPML in and out, categories intact - Filter rules mark, star, or tag articles as they arrive - Feed Health shows a source that quietly died - Load Full Article Text for feeds that only send a teaser PRIVATE BY DESIGN No account, no subscription, no ads, no analytics, and no tracking. Articles stay on your devices. Your subscriptions and what you have read and starred follow you between your Mac, iPhone, and iPad through your own iCloud account. The app fetches feeds directly from the publishers you subscribed to.

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.
Hypothesis 1
Implement a personalized feed algorithm based on user preferences and reading history.
Assumption to check: Lack of personalization in article recommendations
Validate with people who use this workflow before building.
Hypothesis 2
Add a feature for users to save articles for offline access.
Assumption to check: No offline reading capability
Validate with people who use this workflow before building.
Hypothesis 3
Enable sharing articles via social media and messaging apps.
Assumption to check: Limited sharing options for articles
Validate with people who use this workflow before building.
Hypothesis 4
Introduce a text-to-speech feature for users to listen to articles.
Assumption to check: No text-to-speech functionality for articles
Validate with people who use this workflow before building.
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.
