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

Write Only is dedicated to creative writing rather than busy editing. It helps you focus more on putting words on paper. Using it is like sitting in front of a typewriter and watching words flow out of your finger tips. Everything you put down on the page is permanent. All the typing is saved as a PDF file, including the positions, the font size, and the colors that the texts come out with. No matter where and when you are going to view these pages, they will be kept exactly same as the time you typed them. Fixed cursor sits right above the keyboard, therefore your eyes will be close both to the text you're typing and the fingers, and that can help to reduce typing errors. You can start typing on the page at any place by tapping on that location and use any margin you want by moving the page. It is very easy to type aligned texts. An extension keybar includes frequently used keys like ' or ; that are difficult to access in iOS' default keyboard. Write Only is good for writing the first draft of any work, especially poetry, diary or journal. When you come back to your writings years later, the shapes of the text and the errors you made will help you recall the moments of the writing. FEATURES - Sync with iCloud Drive - Beautiful typewriter font. - Minimal interface. - Saved as a PDF file that you can print to paper. - Accessory keybar contains frequently used keys missing in the default keyboard. - Two text colors: black and red.

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.
