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.

What Plane? was built to answer one question—fast: what’s that aircraft overhead? Everything is designed for instant glanceability, so you can get the answer without “using an app”. Add the widget to your Home Screen and tap to refresh. Tap the custom aircraft icon to jump straight into the live map. Inside the app, controls stay just as simple. Want different units? Tap any stat (altitude, speed, distance) to cycle through options. The default view lets you explore nearby air traffic, and with a single tap on any aircraft—or the menu button—you can browse rich details for every plane within 30 nautical miles. To keep the interface minimal while adding real information density, What Plane? uses the Compass Ring: the panel border doubles as a bearing indicator, showing the aircraft’s direction relative to you at a glance. And when an aircraft is overhead, the widget brings it to life with airline-specific liveries and aircraft models—so your Home Screen matches what’s in the sky. WHATPLANE PRO (OPTIONAL SUBSCRIPTION) Choose the aircraft you want to spot and get an alert when a match is nearby. Chat with Lookout to ask about aircraft recorded in your area while you were away, and prioritise your matches in Dynamic Island. Pro is a monthly auto-renewable subscription, purchased separately in the app, with a one-week free trial for eligible new subscribers. After the trial, the subscription renews at the displayed monthly price unless cancelled. The local price is shown before purchase. Payment is charged to your Apple Account. Your subscription renews automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your App Store account settings.

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.
