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
Know the moment a sold-out Jelly is back. Small drops sell out fast, and hundreds of collectors wait for every restock. Jelly Tracker watches the stores for you and sends an alert the moment your plush is back in stock, so you can stop refreshing and start collecting. RESTOCK ALERTS • Turn on an alert for any plush and get a notification when it's back • Stores in the UK, US, Europe, Germany, France and South Korea, plus Selfridges • See each plush's restock history and how many collectors are waiting • Browse the latest restocks across every store • Email alerts with Pro and Max FIND ANY PLUSH IN SECONDS • Search by name, SKU or store link, or scan the tag • The heart saves to your Wishlist; the bell turns on an alert YOUR SHELF, YOUR WAY • Show off your collection on oak shelves, a spine wall, a glass cabinet or a simple list • Record when each one came home, where it came from, price, condition, storage and notes • Keep private photos, or share them with the community • Add custom items that aren't in the catalog yet SHOW OFF YOUR JELLIES • Share cards for new arrivals, restocks and your collection • Your own collector card, ready to share COMMUNITY • Product pages with community photos, comments and fellow collectors PRO AND MAX Free covers the essentials. Optional Pro and Max plans are for collectors who want more: • More alert slots • Faster stock checks • Priority alerts, sent before Free • Email notifications • Market insights: total watchers and full sales history • More private photo storage • No ads A subscription does not guarantee item availability or a successful purchase.
