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
The Ultimate Control Experience for your Denon or Marantz Receiver. Join our discord community: discord.gg/UmVtxE5fXN Join our facebook community: https://www.facebook.com/groups/avrmaestro AVR Maestro is a premium, high-performance mobile controller designed for AV enthusiasts who demand absolute precision. Moving beyond basic volume and input switching, AVR Maestro gives you deep access to the most advanced settings of your receiver - all through a beautiful, dark-themed interface optimized for your modern home theater. UNMATCHED CONTROL & CALIBRATION While other apps only scratch the surface, AVR Maestro provides full visibility and control over your system’s most critical processing: Audyssey MultEQ: Toggle Dynamic EQ, Dynamic Volume, LFC, and Containment on the fly. Dirac Live: Instantly switch between filter slots to match your listening content. Immersive Audio: Fine-tune IMAX Enhanced crossover settings and Auro-3D processing strength. Speaker Levels: Independently adjust gain for every channel, including height and subwoofers, for perfect real-time balancing. COMPLETE SYSTEM MANAGEMENT Multi-Zone Mastery: Independent power, volume, and source control for Zone 2 and Zone 3 from a single dashboard. Virtual Remote: A high-response D-Pad and transport control layout that makes your physical remote obsolete. Quick Selects: Recall your favorite input, volume, and sound mode combinations with one tap. System Deep-Dive: Manage HDMI settings, 12V triggers, eco modes, front panel dimming, and Bluetooth transmission settings. PRIVACY-FIRST, LOCAL PERFORMANCE MiyaraHub Technologies believes your home infrastructure should be private. No Cloud, No Account: AVR Maestro communicates directly with your receiver over your local Wi-Fi. No external servers, no mandatory sign-ups, and no data tracking. Zero-Latency Response: Uses native HTTP and Telnet protocols for near-instant feedback and real-time volume streaming. Album Art & Metadata: View "Now Playing" information and high-resolution album art via HEOS protocol integration. COMPATIBILITY AVR Maestro supports all networked Denon and Marantz AV receivers from the last 10+ years that support IP control. The app automatically detects supported features upon connection.

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.

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.
