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.

VehicleTrax: Your Complete Vehicle Management Solution Take Control of Your Fleet with Confidence VehicleTrax is the comprehensive vehicle tracking and maintenance management application designed for vehicle owners who demand precision, organization, and insight. Whether you manage a single car, an RV, a work truck, or an entire fleet, VehicleTrax transforms scattered receipts and mental checklists into a powerful, actionable database that follows you everywhere—synced seamlessly across your iPhone, iPad, and Mac via iCloud. Why VehicleTrax? Every Mile, Every Dollar, Every Detail—In One Place Stop juggling spreadsheets, shoeboxes of receipts, and forgotten service intervals. VehicleTrax captures everything that matters: - **Garage Management**: Catalog every vehicle (auto, motorhome, travel trailer, utility trailer...) you own or operate with complete specifications, photos, documentation, VINs, insurance details, and tire pressures. - **Fuel Tracking**: Log every fill-up with automatic fuel economy calculations (MPG, L/100km, km/L), cost-per-mile analysis, price trends, and receipt photos. See exactly how each vehicle performs over time and spot expensive patterns before they become problems. - **Trip Logging**: Record business and personal trips with start/end odometer readings, timestamps, purposes, and routes. If you are towing a vehicle (travel trailer, utility trailer, toad...), tick the 'Towed Vehicle' 'option and select the vehicle from the database on the travel log. Milage for this travel log will be updated to the towed vehicles database record and saved as 'virtual milage' to differentiate from actual milage. - **Service History**: Build a complete maintenance record with vendor details, parts used, labor costs, and work-performed notes. Never miss another oil change or tire rotation—VehicleTrax tracks intervals and reminds you when service is due. - **Parts Catalog**: Define consumables and components once (filters, fluids, brake pads) then reuse them across service templates and records. Track costs, preferred vendors, SKUs, and compatibility notes for fast reordering and consistent pricing. - **Maintenance Planning**: Create reusable Service Item templates (e.g., "Oil & Filter Change") with default parts, labor estimates, and intervals. When work is performed, one-tap entry from the template speeds data capture and ensures consistency. - **Systems & Vendors**: Centralize your controlled vocabularies—vehicle systems (Engine, Brakes, Cooling), service categories, and vendor/shop directories—so pickers are clean, reports are accurate, and your data stays organized. Designed for Real-World Workflows - **Multi-Platform Native Experience**: Built with SwiftUI and SwiftData for iOS, iPadOS, and macOS. Enjoy a fast, responsive interface that feels natural on, and adapts to, every Apple device you own. - **iCloud Sync**: Your data is stored locally for speed and privacy, then synced seamlessly via iCloud. Add a fuel log on your iPhone at the pump, review service history on your iPad at the shop, and generate reports from your Mac—all automatically in sync. - **Flexible Units & Formatting**: Configure once, display everywhere. Choose your preferred distance (mi/km), volume (gal/L), fuel economy (MPG, L/100km), currency, and date formats. Vehicle-specific units drive calculations while global settings control reports and exports. - **Rich Attachments**: Capture photos of receipts, invoices, vehicle damage, work performed, and installation guides. Store up to five images per fuel log, trip, service record, part, or vehicle—synced and searchable across devices. - **Professional Reporting**: Generate PDF exports for any vehicle or your entire fleet. Group by date range, vendor, system, or category.

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.
