Generating… usually about a minute.
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.

COURSE COVERAGE Aerial course downloads currently support the contiguous United States. Search shows courses in our reviewed catalog. Coverage is limited and does not include every U.S. course; additional courses become available after validation. Check the supported-course list before purchasing: https://cranecourse.github.io/crane-course-support/#coverage Distances are straight-line GPS estimates to mapped green positions, not a live pin location. Course maps and tee positions may differ from conditions on the ground. Check course signage and conditions as you play. ALSO INCLUDED: OFF COURSE A game while you wait. Off Course is a 3D golf game of Lakeside Country Club (Penn Yan, NY), built into the app: all 18 holes from real course shapes, aerial imagery and lidar elevation. Free with the app, no download needed, works offline. Requires iOS 17 or later. The included Apple Watch companion requires watchOS 10 or later; set up the course and tee on iPhone first.

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.

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.
