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.

No in-app purchases! You get a premium version with all features ads-free. All settings are made through an app on Apple Watch. Watch app part must be installed and the usage of Complication on Watch Face is recommendable. Supporting iPhone app works in the background and can even be completely terminated, as long as the location access has been set to Always (first you select While Using the App, later you are asked to allow Always access).  For any questions or comments please write to: [email protected] ----------------------------------------- Note: It's advisable that you don't setup location accuracy setting more accurate than 100 meters (default). If you have WiFi enabled, this will be good enough to position your iPhone to exact location in urban areas. If you change location accuracy to 1 or 3 kilometres, the app will not even use GPS for location updates, so it will consume less battery, while still doing their job.

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.
