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.

Some pilots, at the critical moment, switch off their targeting computer and go with their gut. Yours now tells the time — so maybe leave it on. A wireframe tunnel. Red range lines closing in. A crosshair that locks on and holds. Stay On Target turns your Apple Watch into a 1970s vector targeting display, with the time underneath in a big angular red readout. It is, technically, a clock. Spin the crown and the radio crackles — short pilot callouts, recorded for this app. Tap the date and your week scrolls away into the distance as a text crawl: today, tomorrow, and every day after that with something on it. Drag it with a finger or spin the crown to move through at your own pace. Nothing booked? It says so, and it sounds pleased for you. WHAT IT DOES - Always-on display: the clock keeps time while the animation rests - Amber or phosphor green — tap to switch cockpits - Radio callouts on the crown, silenced with one tap when you're in a meeting and your wrist starts talking - Mission Briefing: your week's appointments as a receding crawl — drag or spin to scrub through it - Rings, steps, resting heart rate and last night's sleep, read straight off the watch - 12 or 24 hour, whichever way you were trained - Runs entirely on the watch. No phone app, no account, no setup - Collects nothing. We genuinely have no idea who you are Tip: Settings → General → Return to Clock → 1 hour. Now it stays up like a real watch face every time you raise your wrist. Don't get cocky. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
