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

• Apple “New Year, New You” Favorite • Apple App Store Staff Favorite Lumen Trails lets you take notes, make lists and keep track of other things in your life such as time, workouts, expenses, calories, food, weight, sleep or anything else you can think of, even where you've parked your car. Thousands of people use it every day, and they love it because it truly makes a difference in their lives. “I've been using Lumen Trails for 6 months and continue to love it. One of my most sticky and useful apps ever on my phone.” – David D'Souza The beauty of Lumen Trails is that you can track absolutely anything. There are tons of other apps that allow you to track one or two things, for example, calories and weight. But what if you decide to track something else? Say, how many cigarettes you smoke as you try to quit, your eating habits or even net worth? Lumen Trails is the app for that! Instead of having one app for your to-do lists, one for tracking expenses, another one for tracking your weight, you can declutter your home screen and just have one app that does it all. Designed exclusively for the iPhone, iPod touch, and iPad, Lumen Trails is incredibly powerful, easy to use, and looks beautiful on the Retina Display. It can even backup your data automatically to Google Drive, sync with iCloud, and is fully accessible with Apple VoiceOver in 8 languages. There's nothing that comes even close to it. And to top it all, your data is not locked on your iPhone. You can export it to Excel or Google Docs. So what's truly important to you right now? Your Health? Fitness? Finances? Productivity? Track it and get things done! :: Have a Question? We are here to help. Email us at [email protected], or find us on Twitter @lumentrails.

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.
