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
SameSpot: Projects | Precision photo comparison tool designed for tracking progress on any project. Capture a before photo, then overlay it on your after photo to see exact differences. Whether you're renovating a kitchen, redecorating a room, or documenting landscaping work. The app's core feature is real-time overlay alignment with live opacity control. Take your after photo with the before image overlaid at your chosen transparency level, ensuring perfect composition every time. Use built-in rule-of-thirds guides to frame shots identically. Then compare them side-by-side with an adjustable slider to see precisely what changed. Everything stays private on your device, no cloud sync, no analytics, no data collection. Create multiple projects and update them anytime. Replace photos, adjust opacity, and save to your camera roll whenever you want. Perfect for renovations, DIY projects, construction progress tracking, furniture arrangement, painting work, and any project where precise before-and-after comparison matters. This app uses Apple's standard End User License Agreement (EULA). https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
