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
ChatterBox Pro is a local-first AI workspace for iOS. Run compatible local models, manage GGUF files, sideload your own models, connect to remote endpoints, attach documents, use optional web search, tune generation settings, and export cleanly in text, Markdown, or PDF. Built for people who want more control over AI, ChatterBox Pro gives you flexible model choices without requiring a subscription. Use Apple Intelligence when available, run compatible local models on-device, or connect to user-configured services such as Ollama, LM Studio, or OpenAI-compatible endpoints. ChatterBox Pro is designed around control: - Choose local, remote, or Apple Intelligence where available - Manage downloaded and sideloaded models - Tune context, response length, and sampling settings - Attach documents and use relevant context - Export chats as text, Markdown, or PDF - Use optional memory across chats - Lock sensitive chats - Use off-the-record mode - Configure web search only when you want it AI responses may be inaccurate. Verify important information before relying on it. Model compatibility and performance vary by device, model, and settings.

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.
