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.

Cadre Contacts cleans, organizes, and enriches your address book without ever sending your data off your device. It works with your iPhone’s built-in Contacts so you can spot issues, fix them quickly, and keep everything local. Cadre makes the first pass for you: it detects duplicates, highlights fields that need attention, and suggests concrete fixes. You simply tap, review, and move on. KEY FEATURES Health Score Get a clarity score from 0 to 100 for every contact based on completeness and data quality. Tap the score to see exactly what’s missing or inconsistent and what to improve next. Duplicate Detection Find duplicates by comparing phone numbers, emails, names, addresses, and organizations. Review duplicates side-by-side and merge with one tap. Cadre works across iCloud, Google, Exchange, and other accounts connected to your iPhone. Field Validation Catch problems before they become annoying. Phone numbers are checked against formatting conventions for 240+ countries. Emails and addresses are validated against real-world standards so you can correct bad entries early. Smart Fix Suggestions Cadre proposes practical improvements for every field, including consistent formatting. Accept, dismiss, or edit suggestions as you go. It remembers what you do not want, so you are never prompted with the same change twice. Export & Backup Export your contacts to common formats your other apps can read. Back up before bulk operations, so you stay in control of your data, your format, and your file. PRIVACY THE REAL KIND No server. No account. No analytics. No tracking. All processing happens on your device. Cadre reads from Apple Contacts and nowhere else. We couldn’t see your data even if we wanted to. That’s not a policy, it’s the architecture.

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.
