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

It's broken. Dusty. Hazy. But from those imperfections, something beautiful emerges. Dark Park is a generator of cinematic pads and drones, sounds that feel like they're decaying, collapsing, breathing. It's designed for exploration and instant inspiration. When you enter the park, you're given a navigation device. Tap "Scan", and the world beneath the surface generates a new synth patch. Every result is guided by musical constraints, so even the broken ones remain beautiful. If you find a sound you like, you can save it as a preset. There are two paths through the park. Take the Clear Path for delicate, melancholic textures. Or wander down the Obscured Path, and discover sounds that ache. The interface gives you a curated set of controls: Fog. Halation. Sodium. Spray. Pressure. And of course, the familiar ADSR controls to shape the sound further. Play Dark Park as a standalone instrument, or combine it with your favourite effects to create dark ambient music or arthouse cinematic scores. Feature list: - Cinematic synth engine designed for dark ambient, tension beds, drones, pads and atmospheric scoring. - Instant scene generation for fast discovery of new sounds. - Carefully voiced macro controls for shaping mood, depth, motion and character. - Fog control for darker or clearer overall tone shaping. - Halation and Sodium controls for analogue glow, slow evolution and atmosphere. - Spray and Pressure controls for texture and low-end weight. - Full ADSR envelope control. - Hold mode for sustaining evolving drones hands-free. - Built-in on-screen keyboard with octave shifting. - Scene browser for loading, saving and managing custom scenes (presets). - AUv3 support for use inside iPhone and iPad hosts. - Also compatible with Mac devices and supporting DAWs. - Standalone app for direct play without a host. - Designed to produce inspiring sounds quickly without menu diving. Important Information: • Device Layouts The standalone iPhone version and iPhone AUv3 versions are fully optimised for the iPhone screen. The iPad standalone app, desktop version, and AUv3 plugin use a fixed 1:1 interface layout. • Focused Sound Design Dark Park is intentionally designed with a specific sonic identity: cinematic, dark ambient pads and drones. It is not a general-purpose synthesiser and does not aim to recreate every type of synth sound. • Instrument Philosophy Think of Dark Park as a dedicated hardware instrument or soundbox. It excels within its intended palette rather than covering all synthesis styles. • Effects & Processing Dark Park contains no built-in effects. For best results, especially within ambient genres, use external processing such as reverb and delay.

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.
