Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

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.

Differentiate and validate

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.

App Store description

Own your notes — forever. Notebooks is a writing and organization app with no subscription, no lock-in, and no worries. Your documents are stored as standard files you can always access, export, or move freely. Pay once. Use for life. Use Notebooks as a personal wiki, Zettelkasten, document archive, task manager, or long-term writing space. Capture quick notes, turn them into actionable tasks, combine text fragments into chapters, organize research, or keep business documents separate from personal journals — without ever switching apps. Designed to help you stay focused and work at your own pace, Notebooks grows with your needs and is always ready to support you. WRITE AND CREATE Create beautifully formatted documents with styles, attachments, tables, checklists, and optional tables of contents. Choose from ready-made styles or design your own. Write in different ways: Formatted text (WYSIWYG) Plain text, with smart handling of lists, automatic character pairing, and a focused writing view Markdown, supporting MultiMarkdown and Discount, with syntax highlighting, dedicated keyboard keys, wiki-style links, and interactive checklists Sketch ideas or annotate images and PDFs using Apple Pencil. STORE AND ORGANIZE Notebooks stores all documents as regular files in standard formats. You always remain in control — no lock-in, no export worries, fully compatible across devices and over time. Organize your work in books and nested hierarchies without limits. Import PDFs, emails, web pages, MS Office and iWork documents, images, audio, video, and more. Use full-text search to find even the most deeply nested document. PLAN AND ACT Turn books into project lists and documents into tasks. Assign due dates and alerts, create nested projects, and track progress naturally — right where your work lives. Use simple checklists in formatted documents or Markdown for lightweight task tracking. STAY FOCUSED Link documents together to build knowledge over time. Use wiki-style links, backlinks, contexts, and smart books to keep everything connected and within reach. When you rename or move documents, links stay intact. A PLACE YOU CAN RELY ON Sync your documents between iPhone, iPad, Mac, and PC. Work on documents stored in other apps, compile selections into PDFs or eBooks, scan documents and extract text using OCR, and trust that your data stays accessible — now and in the future. With time, Notebooks often becomes the one place users rely on to keep everything that matters close at hand. WHAT USERS SAY “Notebooks is a wonderful app — sophisticated in an unassuming way. I feel more productive without spending time managing the app itself.” “You are GTD in every way that makes it efficient — and makes me efficient.”

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

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.
