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

From the creator of Flashnote Derby comes a fun and educational app that helps kids learn about rhythm and how it is written with music notation. Students will love outwitting the nasty crocodile by tapping rhythms correctly. A variety of levels take students from simply keeping a steady beat up through all different types of notes and rests. The humorous gameplay will keep them motivated to master each new concept. Each level of Rhythm Swing has a brief instructional video which explains the new rhythm concept. Students can view and listen to short musical phrases and hear exactly how they sound. In practice mode, you can attempt hundreds of rhythms until they are mastered. Helpful feedback will guide you in fixing any mistakes. When the student is ready, they can progress to the game, which requires precise accuracy. Types of Rhythms Covered: Quarter Notes and Quarter Rests Half Notes and Half Rests Whole Notes and Whole Rests Dotted Half Notes Eighth Notes and Eighth Rests 4/4, 3/4, and 2/4 Time Signatures More levels featuring more complex rhythms are coming soon! Here's what some of our early reviewers are saying... "My students and I LOVED Rhythm Swing. It was a real eye opener as to which of my students could instinctively keep a steady beat." - K. W., piano teacher "This is a great app. I am using it with beginners. It helps to maintain the steady beat ...at different tempos. What makes it different from other rhythm apps is that it requires holding half notes for two full counts, it progresses slowly enough to use with beginners and it uses different tempi in each level. Thank you!" - J. Z., piano teacher "After playing with Rhythm Swing for awhile my students and I have grown to enjoy it. Most of them like the practice section better than the game because they feel less pressure but eventually they all get around to playing the game. I have all positive things to say about it so far... Keep up the great work!" - S. C., piano teacher

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.
