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

Verituner is an advanced piano tuning app for use by professional piano technicians. This new app brings our leading Verituner product line to the best ever platform in its 15 year history. Piano technicians have said that Verituner technology has given them better sounding tunings than they ever thought possible with the fewest steps. Our patented multi-partial technology calculates your tuning to perfectly match each piano’s unique scaling. Automatic hands-off operation keeps you tuning quickly and eliminates tedious pre-tuning measurement steps. FEATURES • Aural Quality Tunings – create well-balanced tunings with the only tuning technology that tunes all the partials on all the notes. • Quick and Accurate Pitch Raises – get close quickly with overpull targets individually calculated from the starting pitch of each note. • Historical Temperaments – get access to over 90 of the best known historical temperaments, or easily key in your own custom temperaments. • Adjustable Stretch – precisely control octave widths with the built-in Styles, or create your own Custom Style to exactly match your aural tuning preferences. • Alternate Standard Pitch – tune to alternate pitches in a wide range of A=392 to A=466. • AutoNote – jump to any note and octave as you tune with automatic hands free tuning. • Saved Tunings - instantly recall prior tunings so you can tune quickly and consistently on frequently tuned pianos. HOW DOES VERITUNER WORK? Verituner measures the inharmonicity of every note while you are tuning, accumulating a detailed picture of the scaling of the entire piano. Then it calculates tuning targets for all the partials of all 88 notes to produce a well-balanced tuning custom fit to the piano. By tuning all the partials, the best possible compromise can be reached for every tuning interval, and the need for aural adjustments is substantially reduced. All of this is done completely automatically while you tune – without any extra steps required. CAN I TUNE MY OWN PIANO? The answer is yes! BUT… Piano tuning involved advanced skills and experience. A beginner will be challenged with correctly interpreting the moving tuning displays, and performing very fine tuning pin movements that a professional takes years to perfect. If you are an amateur, please contact us to understand what to expect before purchasing this app. QUESTIONS AND SUPPORT If you have any questions about the Verituner app or need any assistance whatsoever, please visit our website www.veritune.com and contact us by email or telephone. We are always happy to help!

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.
