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

Decaf is a different kind of scroll. While most apps are designed to pull you deeper, Decaf asks you to slow down. To take a breath. To spend a moment with a painting that someone poured their life into creating, and that now belongs to the world. Over 23,000 paintings from nine of the world's great museums are available in Decaf, including works from the Metropolitan Museum of Art, the Rijksmuseum, the Art Institute of Chicago, the National Gallery of Art, the Smithsonian American Art Museum, the Cleveland Museum of Art, the Walters Art Museum, and the Belvedere in Vienna. These institutions have graciously made their collections available through open access programs, offering high resolution scans that do justice to the originals. Van Gogh, Rembrandt, Monet, Vermeer, and thousands of lesser-known works that deserve to be seen. There is no algorithm. No ads, ever. No one tracking what you linger on or skip. You can save a painting to your own private collection, or share one with someone via iMessage, WhatsApp, or email. But you cannot follow anyone, and no one can follow you. What you love is yours alone. This app is possible because of these institutions and their commitment to open access. Tap any institution name to learn more about the work, the artist, or the museum behind it. Decaf was made by a couple who still wanted to reach for their phones, but wanted that reach to feel restful rather than restless. The app is a small commitment to yourself: to ease past those first moments of less-stimulating scrolling, and to find something quieter and more lasting on the other side. At 99 cents, our promise is simple — no sponsorships, no incentives to keep you hooked. It's a one-time investment in a little more peace and focus. We hope you take your time with each painting. Find something you admire that you didn't think you would have. Look at each a little longer than planned.

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.
