Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
Reverbs let us simulate acoustic spaces, but with BLEASS Reverb you can mutate and warp that space in realtime with tactile, hands-on controls. If what you need is great-sounding acoustic simulation then BLEASS Reverb is happy to help. But BLEASS Reverb goes far beyond conventional reverb processors. Its mutable reverb generator, freeze mode, and built-in ducker open doors to whole new worlds of sonic possibilities for you to explore. BLEASS Reverb’s clear, colourful and intuitive interface allows you to focus on the important details of your sound without overwhelming you with countless arcane options and settings. And nor will your iOS device be overwhelmed by BLEASS Reverb’s super-efficient engine. BLEASS Reverb App is an AUv3 plugin. A Desktop compatible plugin (VST3 / AU / AAX) is also available for Windows and macOS. More information, technical specifications and tutorials available on https://www.bleass.com/reverb/

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.
