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.

Fish smarter. Catch more. HookUp is the only fishing app that turns complex real-time conditions into a single, actionable HookUp Score — rated 1 to 10 for your exact location, right now. WHETHER YOU'RE A WEEKEND WARRIOR OR A TOURNAMENT ANGLER, HookUp gives you the edge. No more guesswork. No more wasted mornings. Just clear, data-driven intel for every trip. THE HOOKUP SCORE At the heart of the app is the HookUp Score — a live 1–10 rating that tells you exactly how good conditions are for fishing right now, in the next hour, or tomorrow morning. Hit 9+ and it's Prime Time. Drop below 5 and you'll know to sleep in. PER-SPECIES SCORING Not all fish respond the same way. HookUp breaks scores down by species — Largemouth Bass, Smallmouth Bass, Spotted Bass, Crappie, Catfish, Trout, Bluegill, and more — so you can target what's actually biting today. 14 SCORING FACTORS — ALL WORKING FOR YOU Every HookUp Score is powered by 14 precision factors: • Moon phase & solunar feeding windows • Barometric pressure & pressure trends • Water temperature & clarity • Wind speed & direction • Cloud cover & post-front conditions • Spawn activity & seasonal patterns • Flow rate & water levels • Time of day BAIT ADVISOR Know what to tie on before you leave the house. HookUp matches today's exact conditions to the highest-probability baits — complete with color recommendations — so you're always throwing what fish are responding to right now. 24-HOUR FORECAST TIMELINE See your HookUp Score hour by hour across the next 24 hours. Spot the peak window, plan your alarm, and make the most of every trip — even when time is limited. INTERACTIVE FISHING MAP Layer live Doppler radar, fish sightings, known hot spots, your personal catch heatmap, NWS watches & warnings, and surface wind patterns — all on one map built for anglers. CATCH LOG Track every fish you land with species, length, weight, bait used, and notes. Build a personal history that helps you fish smarter over time.

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.
