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.

Create unique invitations and bring people together for life’s most exciting moments.

Cohost with friends, keep guests in the loop, and capture every memory in a Shared Album. Whether you’re hosting or attending, Apple Invites makes it easy to get the party started. Create beautiful invitations: • Choose a background from a curated set of options or pick a photo from your own library to catch your guests’ attention. • Customize the font of your invitation so it feels just right. • Maps and Weather are automatically added so guests have all the details. • Add a Link tile to share anything relevant to your event, like a registry, potluck sign-up sheet, inspo board, collaborative document, and more. Plan and host together: • Add cohosts so friends and family can join in on the fun, invite guests, and share updates. • Sync events to Calendar automatically so you can easily keep track of what’s coming up. • Post messages in the event to keep everyone up to date on last-minute details. Invite and manage RSVPs: • Invite others with just a link using any messaging platform. • Guests can RSVP in the iPhone app or on the web from any device. • Build anticipation with the countdown widget on your Home Screen. Fuel the party with Music and relive it with Photos: • Add a collaborative playlist so guests get to hear their favorite songs at the party. • Include a Shared Album so everyone can add photos and relive all the best moments from the event. Requirements: • Apple Invites is available for all iPhone models running iOS 18 or later. • Ability to collaborate with Apple Music Playlists requires an Apple Music subscription. • Anyone can reply to invitations. Creation of invitations requires an iCloud+ subscription.

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.
