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.

Keep your private photos, videos, and notes locked away with Vault. Vault is a private gallery for personal items you do not want sitting in your main photo library. Import existing photos and videos, capture new ones inside the app, organize everything into albums, and unlock Vault with a PIN, Face ID, or Touch ID on supported devices. Your content stays on your device. Vault stores your photos, videos, and notes locally and does not upload them to our servers. You stay in control of what you import, whether you delete originals from Photos after import, and what you choose to share. With Vault you can: • Lock private photos, videos, and notes with a PIN, Face ID, or Touch ID • Import from Photos or capture new media directly in Vault • Organize albums, favorites, photos, videos, and notes in one private space • Keep your content stored locally on your device • Share items only when you choose • Delete originals from Photos after import when you want to • Add extra protection after failed unlock attempts with optional Intruder Detector Vault is designed for people who want a simple, private place for personal media and notes without cloud storage, accounts, or unnecessary complexity. Whether you are saving personal memories, sensitive screenshots, private videos, or notes you want to keep out of sight, Vault gives you a clean, focused space protected by your device. Download Vault and keep your private moments private.

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.
