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

Grid Square Life app displays an 8-symbol Grid Square Locator (a.k.a. Maidenhead Locator, QTH Locator) value calculated based on the geographical coordinates obtained from GPS satellites and mobile network. Along with your current position, the app will show information about places of interest nearby - radio beacons, lighthouses, national parks and some random callsigns of the amateurs radio clubs and individual radio amateurs in the area. In addition, geographic coordinates and altitude information are displayed, as well as a compass for orientation on the terrain. The distance to your home location will be available after you set (remember) your home location, or any other location you wish use as a starting point for distance mesurements. To do this, you need to use the application Settings tab. You can change it anytime, anywhere. The relative position of your current square among neighboring squares and the distance to the borders of the square are displayed in an easy-to-understand graphical form - you can see the location of neighboring squares and sub-squares. To see more detailed information about the relative position of neighboring squares and your location within the square, you can use: - Map tab (Internet connection required) - Grid View tab The database is loaded during application installation and contains the following topics: - beacons - lighthouses - national parks and reserves - call signs and displayed in 3 boxes: - In this square - Nearby - In Grid Square You can use scrolling to view. To speak the QTH Locator value in voice or Morse code, tap the corresponding icon on the device screen. Notice! The "Time" application field shows the time of the last location update (not the current time) Please be sure to give permission to the app for Location Services to determine your location. No internet or mobile network connection required except if working with map data.

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.
