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

Haaze 2 is a 16 band stereo widening tool that utilizes three different methods of controlling the stereo width and spatial positioning of an audio stream: • Haas – adds a small delay to the left or right audio channel, creating the perceived effect of the sound arriving from the side that’s reaching the ear first. • Pan – alters the gain level on either audio channel. All 16 bands can be panned separately, so this method is quite equal to the “split EQ” function often found on various well-rounded equalizers. • MS Stereo – controls the output stereo width on each band, from normal stereo signal to mono. There’s also a view for controlling the output gain of all bands separately. New features from version 2.0 and later: • New and more transparent crossover filters • Haas: Better control for each band • Split EQ is now called "PAN" and provides much more control • MS Stereo • Gain • Visualization • Brand new and more intuitive UI for a better work flow. • Several factory presets. Full documentation available inside the app or at https://klevgrand.se/downloads/haaze-docs/ Audio examples and more info at https://klevgrand.se/products/haaze Haaze 2 works both as a standalone app and as an AUv3 plugin.

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.
