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.

ExoSphere is a creative tool for shaping continuous ambient and meditative compositions, based on five independent sound layers that merge into a seamless atmosphere. It provides an effortless way to create a foundation for ambient tracks or even a complete background piece with minimal adjustments. Designed with slow rhythmic structures in mind, it is especially suited for meditative music and calm soundscapes. At the heart of ExoSphere are five complementary sound elements, each contributing a distinct dimension to the evolving sonic environment: Core - Deep, evolving drones that anchor the listener with resonant low frequencies, creating a grounding presence in the body. Flow - A layer reminiscent of an instrument, voice, or choir that forms the harmonic foundation of the composition. Gentle shifts its color and pitch, creating a subtle drifting detune that feels fluid and alive. Grain - Layers of stretched environmental fragments - whispers of wind, water, and space - that envelop the listener in a textured, atmospheric sense of place. Shard – Fleeting melodic fragments that surface and dissolve unpredictably, like echoes of imagined songs, sparking shifting associations and evoking transient images. Glow - High, sparkling tones that flicker like light on water, bringing brightness, clarity, and a gentle radiance to the soundscape. Together, these layers interweave into a living, breathing composition that never feels static. The result is a continuously shifting atmosphere - equally suitable as a meditative backdrop, a creative foundation for ambient production, or a complete standalone piece. Each layer in ExoSphere is sample-based, giving the user complete freedom to define the sonic palette. You can load your own samples into any of the five layers, tailoring the sound to your personal style and creating highly individual, versatile compositions. For a quick start, ExoSphere also includes a built‑in library of curated samples, offering ready‑to‑use material that can instantly generate immersive atmospheres. ExoSphere offers an easy start with a minimal interface: choose a factory preset and quickly refresh it by replacing samples, adjusting presence and tone. You can create new variations with the advanced randomizer, while detailed panels provide full control for those who want deeper customization. ExoSphere is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). ExoSphere works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, ExoSphere can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. ExoSphere has a built-in detailed description of all parameters also available as PDF file on the application site.

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.
