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
Split GPX: Powerful iOS Native Route Splitting for Outdoor Enthusiasts! "Split GPX" routes with ease. Perfect for ultra routes, multi-day trips, epic thru-hikes, multi-stage cycling tours and complex journeys with many sections. Quickly handle files too big for other services, and enjoy seamless integration with Apple Files; all offline with a beautiful UI. Your adventures, your way, right on your device. With split routes you can: - Split large Gpx files to use them with navigation devices that have limited storage space or memory (for example click "Share" on the split file in Files, and open it in Garmin connect, then simply sync with your device! No computer or internet needed). - Create realistic day-by-day itineraries - Toggle position tracking to see exactly where you are on your route - Easily split the split segments even further (useful for tough sections (like hiking up a mountain)) The app also includes: * Support for all types of .gpx files * Very small app size (for easy downloading on mobile data connections)! * Exported split files are optimized for storage space * Data validation to ensure clean, continuous tracks * Accurate route plotting using geodesic paths * Native Dark mode support * Split by: - GPS points per segment - Distance per segment (km/miles) * Two map view options: - 3D Earth view - Traditional Map view. * Share split segments with friends or other devices via the Files app * Optimized to fully utilize devices running iOS 18+

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.
