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
The Beep App is an affordable ride-sharing app for college students. It provides a very simple and easy way for people to get rides around their college town. Riders are provided a simple screen that allows them to find a ride in seconds. Drivers (beepers) are given a simple interface where they manage all the riders in their queue. Riders get the benefit of finding a driver with a short wait, low cost rides, estimated time of arrivals, push notifications of their driver's status. Drivers get the benefit of setting their own rates for riders, managing many riders in line for rides, choosing their payment options, and a simple way to tell riders of their status.

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
Improve ride availability by partnering with more local drivers.
Assumption to check: Limited ride options in certain areas
Validate with people who use this workflow before building.
Hypothesis 2
Offer competitive pricing or lower service fees.
Assumption to check: High service fees on bookings
Validate with people who use this workflow before building.
Hypothesis 3
Enhance app reliability through better backend optimization.
Assumption to check: Inconsistent app performance
Validate with people who use this workflow before building.
Hypothesis 4

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.
