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.

WeatherHub: Real Time Weather isn't just another weather app. It's the only app that gives serious weather enthusiasts and storm chasers the professional-grade data they've always wanted — right in the palm of their hand. STORM PROBABILITY — ONLY ON WEATHERHUB No other weather app tells you the actual probability a storm will impact your area. WeatherHub calculates real storm probability scores so you know not just if storms are coming — but how likely they are to affect you. High Risk. Moderate Risk. Peak Day. You'll see it before the storm does. VELOCITY DATA — UNAVAILABLE ANYWHERE ELSE Wind velocity isn't just speed — it's direction, intensity, and behavior across time. WeatherHub tracks velocity patterns in real time, giving storm nerds and weather enthusiasts the kind of deep wind data that used to live only in professional meteorology software. Now it's in your pocket. CORRELATION COEFFICIENTS — THE DATA NERDS HAVE BEEN WAITING FOR Correlation coefficients measure how strongly weather signals agree with each other. When multiple independent signals align, confidence in the forecast skyrockets. WeatherHub is the only consumer weather app that surfaces correlation coefficient data — translated into plain language — so you understand exactly how reliable today's outlook really is. High Confidence. Multiple strong signals in agreement. You'll know. LIVE RADAR — ALWAYS ON, ALWAYS ACCURATE Watch precipitation move in real time with our live radar overlay. See exactly where rain, snow, and severe weather are right now — updated continuously. No delays, no guessing. FUTURE RADAR — SEE 3 HOURS AHEAD Plan ahead with precipitation forecasts up to 3 hours into the future. Watch animated radar loops so you can see exactly how the storm is moving before it arrives at your door. SEVERE WEATHER ALERTS — NATIONAL WEATHER SERVICE, REAL TIME The moment the National Weather Service issues an alert for your area, you'll know. WeatherHub pulls live NWS alerts and plots them on an interactive map — showing you exactly which zones are under warnings, watches, and advisories. Tap any alert polygon to read the full official details. No other app makes NWS alerts this visual and this immediate. PUSH NOTIFICATIONS Get notified instantly when severe weather is heading your way. Never be caught off guard by a tornado warning, flash flood alert, or dangerous storm again. HOURLY & 7-DAY FORECASTS Plan by the hour or by the week. WeatherHub gives you full hourly breakdowns with temperature, precipitation chance, wind speed, and conditions — plus a complete 7-day outlook with daily highs, lows, and risk levels. WIND & CLOUD COVERAGE MAPS Visualize wind patterns and cloud coverage across your region. See where the atmosphere is churning and where skies are clear — real meteorological data in a beautiful, intuitive display. SUNRISE, SUNSET & GOLDEN HOUR TRACKER Know exactly when the sun rises and sets, and when golden hour begins. Track daylight duration for any date. Perfect for photographers, farmers, outdoor adventurers, and anyone who lives by the light. COMFORT INDEX & SMART RECOMMENDATIONS WeatherHub tells you what to wear and what to do based on real-time feels-like temperature, humidity, wind chill, and heat index. Dress right. Plan right. Live right. COMMUNITY WEATHER ARTICLES Connect with fellow weather enthusiasts. Read and write articles about storms, forecasts, weather phenomena, and local conditions. The weather community, built right into the app. BUILT FOR STORM NERDS WeatherHub was designed from the ground up for people who actually care about weather — not just "partly cloudy." If you track storm systems, study pressure gradients, chase severe weather, or just want to understand what's really happening in the atmosphere above you, this is your app. Every feature in WeatherHub delivers data that professional meteorologists use, translated into something beautiful, fast, and easy to understand.

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.
