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.

Your business card should be as easy to share as it is to design. IntroCard puts your card on your phone, in Apple Wallet, and in front of anyone you meet. And when someone hands you a paper card, IntroCard reads it and turns it into a contact. YOUR CARD, ALWAYS WITH YOU Create a polished digital business card in minutes. Import your details from Contacts or enter them manually, then add your portrait, company logo, accent color, and tagline. Keep multiple cards for different roles or businesses. SHARE IT IN SECONDS Show your QR code and let anyone scan it with their camera. The code contains your full contact card, so the other person does not need any app. They just point, scan, and save you to their contacts. You can also add your card to Apple Wallet, so it is just a double-click away, right from your lock screen. SCAN THE PAPER CARDS YOU COLLECT Point the camera at a physical business card, or import photos of cards you have already taken. Scan a whole stack in one go. IntroCard reads the name, title, company, phone numbers, emails, and address, entirely on your device. Scanned cards stay in the app, not in your address book. Keep them as a tidy collection with notes and photos, call or email someone with one tap, and save them to your iPhone Contacts only when you decide they belong there. REMEMBER WHERE YOU MET Every card you scan can be tagged with the place you scanned it, and the Card Map shows everyone pinned where you met them. Name the place yourself, like a conference or a client office, and find anyone later by searching their name, company, notes, or place. ORDER PRINTED CARDS Generate a print-ready design of your card, with your details on one side and your QR code on the other, ready to send to any print shop. PRIVATE BY DESIGN No account. No sign-up. No tracking. No servers. Your cards, contacts, and locations stay on your device and in your personal iCloud, and card scanning happens entirely on your phone. Nothing you scan or share ever passes through us, because there is no us to pass through. FEATURES - Digital business cards with photo, logo, and custom accent color - QR code sharing that works with any phone, no app needed on the other side - Apple Wallet pass with your card and QR code - Scan physical business cards with the camera, or import card photos in bulk - On-device text recognition and smart field extraction - Location tagging and a map of everyone you have met - Search by name, company, notes, or place - Notes and photo attachments for every card you receive - Call, email, or export to iPhone Contacts with one tap - Social profiles and a document link (brochure, price list) on your card - Print-ready card design for ordering physical cards - iCloud sync across your devices Download IntroCard and never run out of business cards again.

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.
