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

The house exterior in lemon yellow or sun yellow? A bedroom in strawberry red? RAL iCOLOURS shows how things could look. With this app for iPhone and iPad, you can now recolour the objects in your photos with any RAL colour – quickly and easily. In only three steps, anything can be recoloured with RAL iCOLOURS: 1.Take a photo with your iPhone. 2.Select one of 2,328 RAL colours. 3.Recolour the object in the photo. RAL iCOLOURS is as useful as it is inspiring. Painters, architects, graphic designers and Web designers can now make it easier for their customers to make colour decisions. With the RAL Colours app, you can quickly give them a picture of your colour concept. You can present colour designs to your customers on site and display alternatives directly. And you can save your colour selection by project name and send photos of recoloured objects via email. The app’s colour palette includes the RAL CLASSIC and RAL EFFECT colour collections and all of the colours in the RAL DESIGN System – all 2,328 RAL colours. The corresponding L*a*b*, sRGB, CMYK and LRV values are listed for each colour. And RAL iCOLOURS is also compatible with COLORCATCH NANO, the Colorix colorimeter. This device incorporates a revolutionary new technology to accurately measure the color of smooth, structured or patterned surfaces to determine the corresponding color of the preselected swatch. NANO reads and measures 50'000 pixels separately. During reading it eliminates automatically all non-dominant colors such as shade effects and dirty surfaces. For better understanding of the functions and use of the App, please watch the demo on the video first. Link to video: https://www.ral-farben.de/iphone-app-icolours.html?&L=1 The colour values enable the user to make a visual choice of RAL colours. Only the primary standards of RAL CLASSIC, RAL DESIGN and RAL EFFECT shall be used for the preparation and control of RAL colours. RAL is a registered trade mark of RAL gGmbH. The presentation of the RAL colours is based on a licence granted by RAL gGmbH. Please visit www.ral-colours.de for further information. Due to technical limitations, colors seen in this App may not accurately reflect paint colors. To confirm your color choices refer to your color cards. © 2018, RAL gGmbH

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.
