What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

VS provides a creative way to generate beautiful graphical representations of your music projects. Driven by both audio and MIDI data, VS is the visual equivalent of a traditional synthesizer. VS takes the concept of music visualisation to a whole new level of customisation and expression, putting you in control and giving you the power to perform however you want. VS is powered by 8 flexible layers which can use shaders, images or videos, allowing you to create generative graphics that you can interact with and layer on top of each other to create complex evolving visuals. With customizable parameters, a modulation matrix and an array of blend modes, use your audio and/or MIDI to trigger and manipulate your layers accordingly with your music. You can even import and create your own shaders to give your visuals a more personal feeling. As the name suggests, VS - Visual Synthesizer can be played live like an audio synthesizer; use your MIDI keyboard to make each layer come alive with the concept of ‘polyphonic visual voices’. As well as a standalone app, VS includes an AUv3 plugin version, so you can run it directly inside your favourite iOS DAW programs like AUM, Drambo, BAM, Cubasis, Loopy Pro, Groove Rider 2, Logic Pro etc. You can now give your existing projects a visual touch of creativity. Simply route the MIDI and audio of your tracks and watch the magic happen. You can connect your mobile device to an external screen or projector for a live visual performance. If you prefer to create a video for your music, the built-in recorder lets you capture both visuals and audio. Record in landscape or portrait mode, with multiple output resolutions available. We partnered with new media artist ‘Perplex On’ to bring you a factory preset bank full of amazing interactive visuals you can start using right away to create dazzling animations and make your music move in a whole new medium. With an ever growing collection of expansions, you can further augment your visual arsenal with preset packs created by handpicked new media art talents. Features: - 8 Polyphonic visual layers (with blend modes) - 4 voices per layer - 32 built-in material effects - Layer material can be a shader, image or a video - Background layer with solid color/image/video - 4 LFO’s with SIN, SQR, TRI, SAW, S&H and filtered S&H - 2 EG’s with ADSR controls - 4 Dual-mode Audio Modulators (envelope and frequency band detection) - Modulation matrix - Full Screen mode - HDMI output for external screen/projector - NDI output - Built-in audio player with MIDI support - Built-in video recorder - Built-in material code editor for custom material creation - Exclusive factory presets by Perplex On

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
