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

LIBOR is gone. Libor X follows the rates that replaced it. For half a century LIBOR was the most important number in finance: hundreds of trillions of dollars in loans, mortgages and derivatives depended on it. After the rate-rigging scandals it was retired, and every major currency moved to an overnight benchmark built on real transactions. Libor X brings them together in one app. FOUR CURRENCIES, ONE SCREEN • SOFR — United States, Federal Reserve Bank of New York • SONIA — United Kingdom, Bank of England • SARON — Switzerland, SIX Swiss Exchange • TONAR — Japan, Bank of Japan THE TERM SOFR CURVE CME Term SOFR at 1, 3, 6 and 12 months is the closest successor to the old USD LIBOR fixings, and it is what business lending is priced against today. Each tenor gets its own card and chart, and the shape of the curve shows where markets expect the Fed to go. WHAT YOU GET • Daily fixing with the change from the previous day • Full history, from one month to the entire available series • Interactive chart: drag to read the value on any date • All four currencies compared on a single chart • A ranking of who pays the most, updated every fixing • The curve read for you: upward, flat or inverted • Notifications when new fixings are published • Works offline with the last downloaded data • iPhone and iPad, light and dark • VoiceOver and Dynamic Type WHERE THE DATA COMES FROM Every rate comes from the official administrator that publishes it. Fixings are released once per business day and appear here after a short delay. Libor X is an information app and does not provide financial advice. Values may differ from official publications: always verify with the administrator before making decisions.

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.
