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

This app puts the Mayan Dreamspell Calendar in your pocket! "13:20:Sync makes it so much easier to understand and integrate the calendar into every day life. Highly recommend it." The Mayan People have described, in breathtaking precision, the cycles of both the universe and nature around us. They created a harmonic calendar that is synchronized to all those cycles. Following these cycles can help you get a stronger connection with nature around you and become conscious of your essence. This app provides a simple way to sync along those cycles, to raise our frequency and give us a new lens to view both our day-to-day and planetary events. - Did you ever realize that our (Gregorian) calendar is not a harmonic calendar? - Did you know that the moon has 13 (not 12!) orbits around the earth in 1 year? - Why do we live with this irregular calendar? - Are you interested in Astrology? -> All this, and more, is explained carefully in this app. (over 15.000 words on 37 pages) Please note that these text are in English language only. In the New Time, synchronicity is the norm. ///////////////////////////////////////////////////////////////// 5 star rating across the world! ///////////////////////////////////////////////////////////////// "Entertaining as well as enlightening" ///////////////////////////////////////////////////////////////// MORE INFO: www.1320sync.com For the beginner this app is a learning tool because it contains an extensive explanation about Tones and Seals and the synchronizing order of the Mayan Astrology.

I spent years in books doing in hours what I can now do in seconds."

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.
