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
FlightDeck is the flight tracker that shows you what pilots are saying, live. PILOT MESSAGES (ACARS) Read the messages pilots and their airline send each other, decoded live: diversions, medical emergencies, maintenance problems, and the odd joke. Search any flight and day. TRACK YOUR FLIGHT Follow your flight on your Lock Screen: clearance, pushback, takeoff and landing runways, and the plane flying in that becomes yours. 3D MODE The 3D flight tracking you've seen all over social media. Real planes in their airline's paint, gear and all. Nothing else comes close. REPLAY Go back to any flight from the last 30 days and watch it fly again. ALERTS Write an alert in plain English, or draw one on the map. Get notified about emergency squawks and military and government aircraft. ALSO INCLUDED Weather radar, turbulence and pilot reports, D-ATIS, METARs, plain-English NOTAMs, FAA ground stops and delays, active runways, gates, TSA wait times, and approach charts. SUBSCRIPTION FlightDeck requires a weekly or yearly subscription. Payment is charged to your Apple Account. It renews automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel it anytime in your Apple Account settings.

Hypothesis 1
Implement push notifications for real-time updates.
Assumption to check: Limited real-time updates leading to inaccurate information
Validate with people who use this workflow before building.
Hypothesis 2
Improve filtering and sorting options for search results.
Assumption to check: Difficult navigation in crowded flight search results
Validate with people who use this workflow before building.
Hypothesis 3
Streamline user profile with easy access to notification settings and purchase history.
Assumption to check: Inconsistent user profile management features
Validate with people who use this workflow before building.
Hypothesis 4
Provide an ad-free premium subscription option.
Assumption to check: Ads may disrupt user experience
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.

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.
