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
■ Your Camera, Reimagined as a Sci-Fi Movie Scope ■ Lock2Cam overlays a real-time object detection HUD on your iPhone's camera feed, transforming everyday vision into a sci-fi / cyberpunk experience. A near-future scouter, a fighter jet's target view — visuals you'd only see in movies, now on your phone with no special gear. ■ Key Features ■ ● Real-time Object Detection HUD The app detects people and objects in your camera feed in real time, drawing them with neon green frames and rune-style labels that follow each target. The stylized labels add to the sci-fi atmosphere while keeping detected names visually obscured — a deliberate nod to subject privacy. ● Lock-On Animation (Red Vector) Every 20 seconds, a randomly selected target gets a dramatic red lock-on animation — the green frame turns red and zooms in to capture it. This layers extra immersion on top of the standard HUD. ● Fully On-Device Processing All camera frames and detection data stay on your iPhone. Nothing is uploaded, transmitted, or stored externally. Privacy by design. ● Portrait & Landscape Support The HUD adapts automatically to portrait and landscape orientation, letting you frame shots however you like. ■ Requirements ■ iPhone (iOS 16.0 or later) / iPad (iPadOS 16.0 or later) ■ Technical Notes ■ Object detection runs entirely on-device using Apple's Vision framework with the official YOLOv3 sample model (Apple Sample Code License). No cloud services, no third-party SDKs, no analytics. Turn the everyday into sci-fi.

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.

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.
