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

Race Monitor is now free to download and includes access to race results, and live timing for select races! Race Monitor gives racers and spectators alike, the ability to view live timing from hundreds of races and tracks around the world over the internet, or you can view live timing directly from a MyLaps, Westhold, or MotoSponder timing system via the RMonitor protocol. With Race Monitor's live timing, you can view racer lap times as they occur, group racers by category (if multiple classes are racing at the same time), and sort by race position or qualifying position. Want access to live timing for all the races? Simply sign up for a live timing subscription to view live timing from hundreds of races around the world. (A subscription is required to access live timing for most races.) ** Connections directly to an RMonitor server provided by a track may require that you be connected to the track's wireless network ** An in-app upgrade to Race Monitor Plus is available which will unlock additional features including a Heads Up Display for racers (includes historical lap times), and Racer Alerts to let you know when a racer you're following goes on track. - A Live Timing subscription is required to view the live timing of most races. - Live Timing Subscriptions are available in either a monthly recurring subscription for $0.99 USD, or a recurring annual subscription for $4.99 USD. Prices may vary by country. - Your subscription is purchased using your iTunes account and can be used on additional iPhones/iPads/iPod Touches that you own. - Payments will be charged to your account at confirmation of purchase. - Your subscription will auto-renew unless auto-renewal is canceled at least 24 hours before the end of the current period. You may turn off auto-renewal at any time from your iTunes Account Settings. - Subscriptions cannot be cancelled during the active subscription period.

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.
