Generating… usually about a minute.
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.

Professional-Grade Acoustic Preparation & Strike Telemetry System. This is not just another basic counter; it is a high-fidelity acoustic diagnostic laboratory designed for cricketers, equipment managers, and professional bat preparers who demand absolute accuracy. Whether you are breaking in a new cleft or maintaining a seasoned match-winner, this system provides the industrial-grade tools required to visualize your knocking progress with mathematical integrity. Real-Time Acoustic Architecture Stop guessing your compression counts. Our dedicated Live Instrument interface allows you to monitor mallet strikes in real time using a high-fidelity acoustic tracking engine. The advanced algorithm isolates the specific frequency of wood-on-wood impact, providing immediate feedback on strike intensity and count—allowing you to maintain a consistent rhythm throughout your preparation session. Zone-Specific Strike Analysis Precision preparation requires granular data. Visualize your progress across the critical architectural zones of the bat: the Toe, Middle, and Shoulder. Our zone-specific telemetry ensures that every inch of the cleft receives the required compression, preventing edge damage and maximizing the sweet spot's performance through systematic, balanced preparation. Advanced Performance Analytics Visualize your preparation journey with our Advanced Analytics Engine. Review detailed strike density metrics and accuracy trends to understand the specific evolution of your bat's readiness. The Pro tier unlocks the comprehensive analytics suite, authorizing you to archive unlimited sessions, track multiple bats simultaneously, and analyze historical preparation data to identify the perfect baseline for match readiness. Elite Inventory & Maintenance Tracking Professionalism starts with organized equipment. Use our Tactical Inventory module to manage your entire kit independently. Archive your sessions in the History log, documenting total strike counts, session duration, and maintenance milestones within a high-stakes performance simulator. Key Features: High-Fidelity Acoustic Interface: Monitor real-time mallet strikes with fluid animations and instantaneous frequency-tracking algorithms. Zone-Specific Calibration: Isolate and track strikes across the Toe, Middle, and Shoulder to ensure uniform compression and structural integrity. Live Strike Telemetry: Review instantaneous feedback on strike intensity, ensuring your preparation remains within professional thresholds. Advanced Performance Trends: Review historical preparation data with integrated analytics, tracking your progress toward a perfectly knocked bat. Multi-Bat Inventory Management: Manage your entire professional kit in one place, with independent tracking for every bat in your bag. Tactical Session Archival: Record and store comprehensive rehearsal logs and performance data in a dedicated activity history. Premium Cockpit Design: Choose between Pristine Light or High-Velocity Crimson themes for a distraction-free, premium aesthetic. Privacy-First Sovereignty: All acoustic processing happens locally on your device; your audio data never leaves your phone, ensuring absolute privacy.

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.
