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
Code with Claude from anywhere. Your Mac's Claude Code session, mirrored to your iPhone read the output, type back, talk hands-free. Your code never leaves your machines Your code stays on your machines. MobileCoder is the wrapper, not the AI. Your prompts and Claude's responses move between your iPhone and your Mac, encrypted, through a forwarding relay that can't see the contents. We don't store your messages. We don't analyze your code. MobileCoder requires an auto-renewing subscription to use. MobileCoder Pro — 7-day free trial, then: • Monthly: $9.99/month • Yearly: $44.99/year Your subscription auto-renews unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID settings. Any unused portion of a free trial is forfeited when you purchase a subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.mobilecoder.app/privacy.html That single block satisfies both: it labels the app as subscription-required with prices (2.3.2) and puts a functional EULA link in the Description (3.1.2c). Also verify (App Store Connect → App Information): - Privacy Policy URL field = https://www.mobilecoder.app/privacy.html

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.

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.
