What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Bring every screen within reach. TVScreen - Cast & Remote turns your iPhone or iPad into a portable screen-mirroring receiver. On the same local network, it can receive video and audio from iPhone, iPad, Mac, and other compatible AirPlay senders. You can also connect to a compatible Apple TV on your local network. After pairing, view the Apple TV screen on your iPhone or iPad and use the built-in remote for navigation, Select, Back, Home, Play/Pause, and Mute. Key Features: • Receive wireless screen mirroring over your local network • Receive and play compatible video and audio • Mute or restore local audio playback at any time • Tap the screen for full-screen viewing • Capture screenshots and save them to Photos • Record received video with available audio and save it to Photos • Choose a 30 fps or 60 fps recording target • View resolution, frame rate, video, and audio status • Discover, pair, and connect to compatible Apple TV devices • Use a compact built-in Apple TV remote • Remember paired devices or forget them when needed Privacy and Local Processing: Mirroring traffic stays on your local network, and content is processed on your device. Diagnostic logging is off by default. When enabled, only redacted connection and screen status information is stored locally; device identities, ports, and authentication data are not retained. Disabling diagnostic logging clears saved logs. Screenshots and recordings are saved only after you grant permission to add them to Photos. Usage Notes: • The sending device and receiver must be on the same local network • Resolution, frame rate, audio, and remote capabilities depend on the sender, operating system, and network conditions • Compatibility may vary between device models and system versions • Only capture or record content that you own or are authorized to save This independently developed third-party app is not authorized, sponsored, or endorsed by, or affiliated with Apple Inc. Apple, Apple TV, and AirPlay are trademarks of Apple Inc.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
