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

Music Library Tracker keeps an eye on your music library and automatically monitors additions, deletions, and any changes to your songs as well as upgrades to Spatial Audio. With streaming becoming more popular, it is very easy for song metadata to change or for songs to disappear as licensing deals expire; with Music Library Tracker you will always know when something in your library changes. Features - Automatic monitoring of the media library on your iPhone or iPad (including iCloud Music Library if enabled on your device). Music Tracker checks the title, artist, album, album artist, genre, year of release, disc number, track number, rating, and Spatial Audio status. - See which of your tracks have been upgraded to Spatial Audio and have them placed into an automatic playlist within Apple Music. You can also opt-in to receive notifications when tracks are upgraded. - View an overview of changes to your library with filters to personalise the display to your requirements - Drill down into the detail of individual tracks to see exactly which metadata changed and when along with dates for when tracks were added or deleted from your library - A daily notification giving you a summary of changes in the previous day (this can be customised to just tell you about added, changed, or deleted tracks) - Automation via x-callback-url allowing you to see changes to your library in the Shortcuts app or with Siri - Full support for split screen views on iPad along with trackpad and keyboard integration - Dark mode Music Library Tracker contains no in-app purchases and does not require an internet connection; I believe in your privacy so none of your media library data ever leaves your device and I do not collect usage data or perform any data analytics. Spatial Audio matching is "opt-in" as it requires the app to send your music identifiers to my server; no personally identifiable information is ever sent and the data is kept only for as long as it takes to serve the request (typically less than a couple of seconds). You can read more about this in my privacy policy at https://dodoapps.io/music-tracker/privacy/ If you have any issues at all, please email [email protected] and I'll help you.

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.
