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.

Every roll of the dice carries the weight of legend. Spellroll transforms the simple act of rolling dice into a cinematic experience worthy of your greatest adventures. Forged for Dungeons & Dragons players, dungeon masters, and tabletop RPG enthusiasts, Spellroll brings the thrill of physical dice to your iPhone with stunning 3D physics, AI-powered storytelling, and a deep character system that makes every session unforgettable. ROLL WITH REAL PHYSICS Eight beautifully crafted arcane dice types -- D4, D6, D8, D10, D12, D20, D100, and percentile -- rendered in real-time 3D with Apple RealityKit. Each die tumbles, bounces, and lands with satisfying weight. Hold the roll button to charge your throw and build anticipation before releasing your fate to the table. SMART PRESET SYSTEM Access over 30 built-in D&D presets for common rolls: attack rolls, saving throws, ability checks, damage for every weapon type, healing spells, and more. Create your own custom presets with standard dice notation (2d6+4, 1d20+5, 4d6kh3). Pin your favorites to the quick-access tray for one-tap rolling during sessions. CHRONICLE YOUR ADVENTURE Every roll is recorded with its full context -- the dice used, the result, the outcome tier (Critical, Success, Failure, or Fumble), and the AI narration. Scroll through your history to relive the moments that defined your campaign. DESIGNED FOR THE TABLE Spellroll's dark arcane aesthetic -- deep blacks, mystical purples, and warm gold accents -- sets the mood without distracting from your game. Haptic feedback syncs to every roll for a tactile experience that feels like real dice in your hands. SIRI SHORTCUTS Ask Siri to roll your favorite presets. "Hey Siri, roll for initiative in Dice Box" triggers your saved preset instantly, keeping your hands free and your eyes on the table. PRIVACY FIRST All AI narration runs on-device using Apple Foundation Models. No data leaves your phone. No cloud processing. No account required. Your rolls, your characters, your stories -- entirely yours. Download Spellroll and transform every dice roll into a moment worth remembering. Your next critical hit deserves an epic story.

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.
