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

From Theodore Gray comes a beautifully produced app introducing and educating users on the elements of the periodic table and how they combine to form the world around us. The Elements is a rich and engaging love story, told in words and pictures - allowing you to experience the beauty and fascination of the building blocks of our universe in a way you've never seen before. Start off on a living periodic table where every element is shown with a smoothly rotating sample. To read about gold, tap the gold nugget. Immediately you see the sample filling the screen, photographed to razor sharpness and rotating around a complete circle in front of your eyes. Enjoy the extensive array of facts and figures. Next find a fascinating story about the element, surrounded by carefully photographed objects representing it. Every one of these objects, well over 500 in total, is a freely rotatable, live object that you can examine from all sides and pinch zoom to see in unprecedented detail. Touch the element name at the top of the page and you can see that element’s name in over a dozen different languages. Choose one and you’ll find that the entire book, stories, captions and all, switches to that language: The Elements includes both the full English original text and over a dozen full translations. Pinch-zoom or tap any object to bring it up full screen, where you can split into a pair of stereo 3D images, allowing you to see all 500 objects pop off the screen in 3D, and you can spin the objects, in 3D, with the touch of a finger. This book will show everyone there’s a lot more to the periodic table than a bunch of numbers and letters. Features include: • Beautifully composed pages for every Element in the periodic table • Fun stories and fascinating facts • All objects pinch-zoom with amazing detail and rotate in 3D • Engaging introduction explaining the structure of the periodic table • Engaging introduction explaining the structure of the periodic table • Fully translated into English, Catalan, Croatian, Dutch, Finnish, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Simplified Chinese, Spanish, Swedish, Turkish ------------ Reviews: “The iPad’s splendor and power may be best shown by The Elements... it’s not like any ebook you’ve seen. The periodic table of elements comes to life.” – USA Today

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.
