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
Experience your comic collection like never before. Lenticule isn’t just a reader; it’s a state-of-the-art immersion engine designed to bring every panel, every hero, and every story to life with breathtaking detail. NEXT-GENERATION GUIDED READING Forget manual scrolling. Lenticule uses advanced mapping technology to identify every panel on the page, creating a cinematic, focused reading experience. Let the story flow as the app intelligently guides you through the action, one beat at a time. SPATIAL 3D DEPTH Step into the page. Our unique Spatial Engine separates subjects and background layers from flat images. Watch as your favorite characters pop with a subtle, immersive effect that transforms standard 2D art into a living scene. PRO-GRADE HDR RENDERING Lenticule is built for the best displays in the world. Leveraging Extended Dynamic Range (EDR), the app pushes the limits of your screen's brightness and color gamut. Experience vibrant inks, deep blacks, and highlights that truly shine. SILKY SMOOTH PERFORMANCE Our custom tiled-rendering pipeline ensures that even the most high-resolution PDFs and archives scroll with buttery fluidness. Zoom in and catch every hidden detail without a hint of lag. INTELLIGENT LIBRARY MANAGEMENT Organizing thousands of issues has never been easier. Lenticule automatically extracts metadata, generates beautiful high-resolution covers, and offers a premium "Liquid Glass" interface that feels as modern as your device. --- HARDWARE OPTIMIZATION AND COMPATIBILITY Lenticule is designed to scale with your hardware, ensuring the best possible experience across the entire Apple ecosystem. Some advanced features are intelligently adjusted based on your device's capabilities: - Panel & Subject Mapping: Requires a device with at least 4GB of RAM (iPhone 11 or newer, and M-series iPads) for real-time analysis. - HDR/EDR Content: Requires an HDR-capable display (Super Retina XDR or Liquid Retina XDR) to unlock full brilliance. - Ultra-Detail Mode: High-end hardware (6GB+ RAM) unlocks maximum texture resolution and higher zoom levels. NOTE: Lenticule does NOT contain or distribute comics. All comics that you see in the previews are for demonstration purposes only.

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.

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.
