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.

Whateren is a beautiful, private home inventory app that runs on your device by default. Finally know what you own, where it is, and when you got it. Preparing for a move, documenting your belongings for insurance, or just tired of asking "where did I put that?": Whateren catalogs every item, room and piece of furniture in your home. WHAT · WHERE · WHEN • What: every item you own, searchable and filterable • Where: your properties, rooms, furniture and boxes, organized in a hierarchy • When: a timeline of every change to your inventory QR LABELS FOR BOXES AND ROOMS Print a label for any box, drawer or room, or label a whole home in one PDF, on plain paper or on Avery sheets. Scan a label with the iPhone's own Camera and that place opens in the app. The larger labels can list what is inside, and the code itself carries nothing but an anonymous identifier. PHOTOS THAT STAY WITH YOU Take a photo of any item as you add it. Images are optimized on your device to keep storage small. Press and hold a photo to remove its background: the item is cut out and centred on white, on your device, offline, at no cost. AI IDENTIFICATION (OPTIONAL) Use the free, on-device AI (Apple Vision, with enhanced results where Apple Intelligence is available) to auto-fill an item's details from a photo. Or opt into Premium AI (Anthropic Claude) for brand, model and estimated value. Premium is pay-as-you-go with credit packs, no subscription, or bring your own API key. Enhance with AI re-runs identification on an item or place you already added. BARCODE SCANNING Scan a book, food item, or tagged product to auto-fill its details from public catalogs. RECEIPTS AND DOCUMENTS Photograph a purchase receipt and Premium AI reads every product on it: name, price, quantity, category, and the serial number or warranty when the receipt prints them. Choose where the items go and each one lands in your Inbox waiting for its own photo, with the receipt attached to it as a document. One credit per item you import. You can also attach a receipt, an invoice or a manual yourself. INSURANCE REPORTS AND INVENTORY LISTS Turn any room, property, or box into a PDF report for your insurer: everything inside it and its sub-places, with photos, serial numbers, and prices. Or choose a plain inventory list, with the statuses you pick and none of the insurance details. LENDING & WARRANTIES Lend an item and note who has it and when it is due back, then get a reminder. Every item keeps its loan history and its warranty date. FIND IT FROM ANYWHERE A Search tab answers one query across items and places at once: names, serial numbers, barcodes, categories, even the title of an attached document, so a shop's name finds what you bought on that receipt. Search from the Home Screen with Spotlight too, or ask Siri to add an item or find where something is, in your own language. Open an item on one device and it waits for you on the other, in the Dock and the app switcher. iCLOUD SYNC & FAMILY SHARING (OPTIONAL) Turn on iCloud sync to keep your inventory across your Apple devices. If iCloud already holds something, you choose which side is right: combine both, keep what is in iCloud, or keep what is on this device. The app names what each choice costs before you make it, and what was on this device is set aside so you can change your mind. Share a property with family, choosing view-only or full-edit access. TEAM CAPTURE Everyone you share a property with can help capture it: each photo is saved instantly as a draft, AI identifies it as it arrives, and everything lands in the Inbox to review and confirm. YOUR DATA STAYS YOURS Export to CSV or JSON, and back up everything (photos included) at any time. PRIVATE BY DESIGN Whateren has no account, no server of ours, no ads, no analytics, and no tracking. Every network request it makes is named in our privacy policy. Privacy Policy: https://www.whateren.com/privacy

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.
