A product spec, screen plans, and build steps for your coding agent.

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.

BigBlue is the advanced offshore fishing intelligence platform designed to put you on the fish fast. We replace expensive hardware and subscriptions with professional-grade satellite data directly on your phone. Whether you are chasing Marlin in the canyons, Tuna on temp breaks, or Mahi on weed lines, BigBlue gives you the competitive edge. Built by fishermen, for fishermen. WHY ANGLERS CHOOSE BIGBLUE: * Real-Time Ocean Intelligence Don’t rely on outdated data. BigBlue delivers the most comprehensive satellite scans available: Ocean temperature reported by scientific Sea Surface Temperature (SST) sensing satellites: 9 daily scans from MODIS, VIIRS, and GHRSST satellites. Chlorophyll Charts: Identify clear water boundaries and plankton-rich feeding zones (6 daily sources). True Color Imagery: See real ocean conditions, current edges, and debris lines. * Global 3D Bathymetry & Structure Fish live where the structure is. Our high-resolution global bathymetry maps reveal seamounts, canyons, ledges, and drop-offs worldwide. Combine structure data with temperature breaks to pinpoint productive waters/ * 100% Offline Capability (No Signal? No Problem) BigBlue is built for offshore use. The app automatically caches data as you view it. Simply pan over your fishing grounds while on Wi-Fi, and all charts, temp layers, and bathymetry are saved to your device. Navigate confidently 100+ miles offshore with zero cell signal. * Expert Pelagic Habitat Guide Not sure where to look? Our in-app guide provides scientific habitat data for top sport fish. We analyze ideal temperature ranges and chlorophyll concentrations for: Tuna: Bluefin (Atlantic/Pacific), Yellowfin, Bigeye, Albacore, Skipjack. Billfish: Blue Marlin, Black Marlin, White Marlin, Sailfish, Swordfish. Gamefish: Wahoo, Mahi Mahi (Dolphinfish), Cobia, Yellowtail. * Professional Navigation Tools Turn your phone into a chartplotter. Waypoints: Mark your favorite spots and temperature breaks. Distance Calculator: Measure distance to the rip to plan fuel usage. GPS Overlay: See your live position, speed, and heading directly on the satellite charts. NMEA/AIS Viewer: Link the app to your onboard NMEA WiFi network to view nearby vessel details via AIS BETTER DATA, BETTER VALUE Global Coverage: We don't limit you to one region.

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.
