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
SpotSaved — Remember Where You Parked Never circle the block again wondering where you left your car. SpotSaved pins your exact parking spot the moment you step out, so you can always find your way back. Save Your Spot in One Tap The moment you park, hit Save My Spot. SpotSaved captures your GPS location and displays it on a map — no account required, no sign-in, no fuss. Everything stays on your device. Beat the Meter Set a parking timer so you never come back to a ticket. Choose exactly how long you have, set a reminder, and SpotSaved will notify you before time runs out. You can even let the app calculate how long it will take you to walk back to your car based on your current distance. Navigate Straight Back When you're ready to head back, tap Navigate and SpotSaved opens turn-by-turn directions to your exact spot in Maps. Photo Reference Snap a photo of your parking sign, garage level, or surroundings so you always have a visual reminder of exactly where you are. Parking History SpotSaved keeps a log of your past parking spots, so you can look back and confirm where you parked even after you've driven away. Completely Private Your parking data never leaves your phone. No cloud sync, no tracking, no ads.

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.
