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

Use “Contour - Volume - Stakeout” on your iPad, iPhone or iPod touch to generate a contour map of elevations or some other variable of interest. Then you may have volumes computed based on the contour regions. For example, a farmer could record soil data at the sampling points then have the variable of interest contoured over the farm plot. This contour map could serve as a guide in fertilizer application. If there is a mound of land to be leveled, the Volume function could help you compute the amount of dirt to remove based on the elevation data taken over the mound. Also use this app to precisely digitize Points, Lines and Areas over the built-in Map and view their locations, lengths and areas. If your device has GPS capability, you may record the GPS location as a Point, or pick the GPS location as a node for the Line or Area you are creating. Location accuracy depends on the accuracy of the GPS receiver used This app provides Point Stakeout and Line Stakeout functions to help you approach a point or move along a line or area boundary. The contour map can be printed to PDF. The contour data can be exported in a text file format. The Feature data can be exported in Shapefiles and DXF formats. Detailed Function List: * Import Shapefiles, DXF files and text files. * Create a grid and generate sampling points. * Precisely digitize Points, Lines and Areas over the built-in Map. * Use Point Stakeout and GPS to locate a point or a node on a line. * Use Line Stakeout and GPS to locate a line. * View position, length and area values for the Features. * Label the Lines with segment lengths and directions as well as corner angles. * Label the Areas with size in acres and square feet or hectares and square meters. * Measure distances and areas without saving the shapes. * Move existing nodes to fine-tune the map drawing. * Create a Point from entered coordinates. * Create a Point or record a node by picking the GPS location. * Save the job data file for later use. * Export Feature data to DXF or Shapefiles. * Export the contour data to a .CSV text file. * Output the drawing and the coordinates to PDF. * Email the job data files and the PDF files to your colleagues. This app comes with a detailed built-in help document. Please note: Continued use of GPS running in the background can dramatically decrease battery life. This app will let you easily toggle the built-in GPS on or off.

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.
