A product spec, screen plans, and build steps for your coding agent.

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.

Squinting at a QR code that won't scan, or wondering if a link inside one is actually safe to open — that's exactly what QR Code Pro solves. Point your camera at any QR code, barcode, or NFC tag and get an instant, accurate read, then create and customize your own codes just as fast. One purchase, every feature, no ads, ever. INSTANT SCANNING Turn your iPhone into a fast, accurate scanner. Point the camera or import a photo, and QR Code Pro recognizes 13 formats in seconds: QR, Aztec, Data Matrix, Code 128, Code 39, Code 39 Mod 43, Code 93, EAN-13, EAN-8, Interleaved 2 of 5, ITF-14, PDF417, UPC-E Ultra-wide camera support makes it easy to scan large or hard-to-reach codes, and batch scanning lets you capture several codes in one pass instead of stopping after every one. SAFER LINK CHECKS Before you open a scanned link, QR Code Pro checks it for you — flagging disguised domains, link shorteners, unsecured HTTP connections, and unusually long or suspicious URLs, so you can decide with confidence whether to tap through. NFC SCANNING Read compatible NFC tags with your iPhone, including tags that store more than one record — every record reads correctly and displays in full. CREATE AND CUSTOMIZE QR CODES Build a QR code for a website, Wi-Fi network, contact, phone number, email, SMS, text, location, or calendar event in a few taps. Make it yours with custom colors, eye shapes, pupil styles, and your own logo — perfect for a business card, a menu, a classroom, or an event. PRINT & SHARE Print QR codes directly from your iPhone with adjustable layouts, or share them digitally for packaging, flyers, posters, and product labels. STAY ORGANIZED Unlimited scan history keeps every past scan within reach, and Favorites keep the codes you use again close by. iCloud sync carries your history and created codes across your Apple devices, and you can set Scan, Create, or History as the tab that opens first. ONE PURCHASE, EVERYTHING INCLUDED QR Code Pro is a single purchase — no subscription, no in-app purchases, and no ads, ever. Every feature above is included from the moment you install it: - Scans QR, Data Matrix, and 13 barcode formats - Ultra-wide camera support for larger or farther-away codes - Batch scanning for multiple codes in one pass - Safer Link Checks before you open a scanned link - NFC tag reading, including multi-record tags - QR code creation and customization with your own logo - Direct printing with adjustable layouts - Unlimited scan history and Favorites - iCloud sync across your Apple devices - Choice of default tab on launch - No subscription, no in-app purchases, no ads People use it to check a restaurant menu, verify a delivery code, build a QR for a Wi-Fi password or business card, or just confirm a link is safe before opening it.

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.
