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
In the chaos, cultivate inner peace. InkZen is not a tool—it's a journey inward. Through the aesthetics of traditional Chinese ink art, find stillness anytime, anywhere. Ink Drying · Focused Presence Watch ink slowly diffuse on rice paper, or incense ash gently drift—time becomes tangible through the breath of ink. Each session creates a unique zen card capturing your state of mind, to share or keep. Ink Diffusion: Witness time's texture as ink spreads Incense Burning: Watch ash fall as your mind settles Zen Cards: Each focus session generates unique ink art Live Activities: "Ink Drying" aesthetic timer on Dynamic Island Digital Calligraphy · Water & Ink No pen, no paper—your finger is the brush. Authentic ink diffusion and water effects create realistic Chinese calligraphy. Water Mode: Strokes fade instantly, like life's fleeting moments Permanent Mode: Save works as beautiful calligraphy cards Widgets: Your brushstrokes live on your home screen Soundscapes · Nature's Voice High-quality nature sounds, algorithmically generated to never loop—like true wilderness, perpetually fresh. Paired with meditative animations. Temple bells, rain on leaves, mountain winds Infinite variation, never repeating Visual harmony: Sounds dance with animations Petals Fall · Heaven's Will When doubt clouds your mind, let fate decide. Tap the screen, watch chrysanthemum petals drift, and your heart will find clarity in their fall. Each bloom is unique, each reading a moment of fate Surrender to the flow: Beauty lies not in the answer, but in letting go The ritual of trust: Sometimes the wisest choice is to choose nothing Perfect for: Students & professionals needing deep focus Lovers of Chinese culture and ink art Urban dwellers seeking calm amid chaos Release anxiety. Enter stillness. InkZen—your pocket meditation hall.

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.
