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
DUMP STATIONS, WITHOUT THE GUESSWORK The tank is full and the next station is either four miles away or forty. Dump Station Finder opens straight to a map of RV dump stations around you. No password to remember, no wading through a complicated app. FIND ONE NOW • See every dump station near you on one clean map • Search any city, ZIP, address, or place to scout a stop before you drive it • Zoom out to plan the week, zoom in to pick tonight's stop • Tap a pin for the full listing KNOW BEFORE YOU PULL IN Listings come from Campendium's moderated RV database: the same data behind an app rated 4.8 by more than 20,000 RVers. • Reviews from RVers who actually dumped there • Photos, so you know what you're pulling into • Free or paid, stated plainly • Full address and GPS coordinates, tap to copy into any nav app • Phone number and website, when the station has them • The details that decide it: restrooms, big-rig access, accessibility, credit cards KEEP YOUR REGULARS Bookmark a station and it's saved on your device: the rest area you always use, the truck stop on the way home, the county park that's still free. No account, no sync, no losing them. SPOTTED ONE WE'RE MISSING? Settings → Submit a dump station. RVers keep this data honest, and every submission gets read. Dump Station Finder is made by the team behind Campendium.

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
Show total price upfront including all fees
Assumption to check: Hidden fees revealed at checkout
Validate with people who use this workflow before building.
Hypothesis 2
In-app chat with fast response times
Assumption to check: Poor customer support
Validate with people who use this workflow before building.
Hypothesis 3
3-step booking with clear progress
Assumption to check: Complicated booking process
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.

BUILD KIT DIFFICULTY
Intermediate
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.
