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.

Remember the places that made the trip. Known Ground is a private travel journal and photo map for your trips, walks and memories. Keep the street you stumbled on, the view you came for, and the details you want to remember, together with the places they belong. KEEP THE TRIP TOGETHER Bring your photos, visits, routes and notes into one trip. Return to a day through the places you explored and the memories you kept. REMEMBER MORE THAN THE VIEW Keep trip photos connected to their places. Add a few words about what you noticed, why you stopped, or what you would do next time. SAVE THE PLACES YOU WOULD GO BACK TO Save places for later, record visits when you go, and keep notes and photos with a particular visit. Build a map of the places you know. KEEP THE WAY YOU WENT Record your explorations with Trip Coverage or a focused Apple Watch walk. Import walking, running, hiking and cycling routes from Apple Health. Health imports and their trip assignments stay on the device where you import them. FIND YOUR WAY BACK TO A MEMORY Search by place, trip, note or photo context. Find Known Ground memories in Spotlight, too. PRIVATE, WITH ROOM FOR YOUR PEOPLE Your library is private unless you choose to share. Invite people to a trip through iCloud, choose which memories to share, and use owner, editor or view-only access. No public profile, social feed, ads or cross-app tracking. For iPhone, iPad and Apple Watch. No app-specific account is required. iCloud sync and private trip invitations use your Apple Account.

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.
