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

Resolve is a powerful ear training system, developed by Tom Quayle and David Beebee, combining a structured video course with a custom practice tool. The course and practice tool are designed to work together: the videos explain the concepts and exercises, while the practice tool generates the harmonic material you use to train your ear on your instrument. Reactive Ear Training focuses on developing a direct connection between your ear, your fingers, and your instrument. Resolve generates random, non-functional chord voicings for you to react to by playing over each chord using the exercises taught in the inlcuded course. The Harmonic Complexity Slider lets you tailor the sounds to your ability, from simpler, more consonant voicings at lower settings to increasingly complex and dissonant sounds at higher settings. Practicing this way strengthens the connection between your ear, your fingers, and your instrument. Over time, this develops stronger musical instincts and a deeper, intuitive understanding of harmony that maps directly to your instrument and translates to real musical situations. Key Features ‣ Created by Tom Quayle and David Beebee Resolve was developed as a complete Reactive Ear Training system, combining a structured video course with a practice tool designed to work together. ‣ Integrated Video Course and Practice Tool The course explains the method and demonstrates the exercises, while the practice tool generates the harmonic material you react to on your instrument. ‣ Random Harmonic Voicings Generate non-functional chord voicings to react to in real time. This approach strengthens the connection between your ear, your fingers, and your instrument. ‣ Harmonic Complexity Slider Tailor the sounds to your ability, from simpler, more consonant voicings at lower settings to increasingly complex and dissonant sounds at higher settings. ‣ Train Real Musical Instincts Resolve is designed to be used without naming or labelling chords, scales, or intervals. By focusing purely on sound, you learn to respond directly on your instrument. With some familiarity of major and minor sounds, you can begin immediately. ‣ Complements Functional Ear Training Designed to support your ongoing study of harmony, scales, chords, and functional ear training. ‣ Designed for Use With Your Instrument Built for active playing, helping connect what you hear directly to movement on your instrument. Resolve works for: ‣ Guitarists ‣ Bassists ‣ Pianists ‣ Any instrumentalist developing their ear Whether you’re improvising, composing, or learning music by ear, Resolve – Reactive Ear Training helps you develop faster and more reliable musical instincts.

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.
