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.

It works alongside technologies like Cascading Style Sheets (CSS) and JavaScript. CSS (Cascading Style Sheets): A style sheet language used to define the presentation of documents written in HTML or XML. CSS is a core technology of the web, enabling developers to customize the appearance of web pages. JavaScript (JS): A versatile programming language that powers web page behavior on the client side. As of 2022, 98% of websites use JavaScript, often alongside third-party libraries. HTML is essential for structuring web documents (web pages), while CSS defines their appearance. Together, they form the backbone of web design. HTML Editor makes it easy to read or edit HTML files stored on your iOS devices. Test your HTML/CSS code on the go or experiment with JavaScript code directly from your mobile device. Thank you for your support! Visit nitrio.com for more apps designed for your iOS devices.

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.
