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.

Most weather apps show you what a computer model thinks. KC WeatherNOW shows you what a meteorologist knows. Built exclusively for Kansas City by Meteorologist Wes Peery, KC WeatherNOW combines professional forecast expertise with hyperlocal data sources unavailable on any national platform. Every forecast is informed by a meteorologist who actually understands KC weather patterns. Features What Matters Today Plain-language weather summaries written by a broadcast meteorologist — updated three times daily for morning, afternoon, and overnight. Not raw data — actual insight about what the weather means for your day in Kansas City. Storm Awareness & Alerts Tap ME to drop your location pin on the radar. The moment you fall inside an active NWS watch or warning, a color-coded banner appears — "You're inside a Tornado Warning." Real push notifications for severe weather and approaching storm cells, personalized to your location. One simple on/off toggle. No duplicate alerts. Aches & Pains Barometric Pressure 24-hour observed and 5-day forecast pressure chart with plain-language health context for joints, sinuses, and migraines. Allergy Outlook The only KC weather app with hospital-verified, plant-specific daily pollen counts from Children's Mercy Hospital's Department of Allergy and Immunology. Includes a trend indicator showing whether pollen is rising or falling. Push Notifications Real iOS push alerts for severe weather and approaching storm cells — personalized to your location. Daily morning briefing option delivers that day's forecast to you at 6, 7, or 8am. Alerts when the pollen count reaches high levels Activity Forecasts Meteorologist-informed outlooks for golf, fishing, hunting, yard work, and eating outside. Lightning on the Radar See real-time lightning strikes overlaid on the radar map. Strikes fade over time so you can track storm movement and intensity at a glance. Future Radar 3-hour HRRR-powered future radar — see where storms are headed before they arrive. Interactive Radar Full-screen NEXRAD radar with real-time updates, storm cell tracking so you know what storms could produce hail or a tornado soon Severe Weather Alerts Instant NWS alerts with full-screen emergency overlay when a warning covers your location. Lake Forecast Weekend forecast for Table Rock, Lake of the Ozarks, Truman, and Perry lakes — wind, water temperature, and chop indicators for boaters and anglers. Includes solunar peak times for fishing and hunting planning. Hourly & 10-Day Forecasts 48-hour forecast with larger rows, sunrise and sunset times, and rain chances next to each hour. Full 10-day outlook informed by a meteorologist, not just an algorithm. KC Sports Weather Game day weather forecasts for the Royals, Chiefs, Sporting KC, and KC Current — so you know what to wear before you head to the stadium. Muggy Meter Because 90° in KC feels nothing like 90° anywhere else. Current Conditions Real-time temperature, feels-like, wind speed and direction, barometric pressure, UV index, and precipitation totals — updated continuously. Share Your Forecast Snapshot and share current KC conditions as an image directly to social media, messages, or anywhere else.

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.
