Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
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.

YOUR LOCAL WEATHER SERVICE WillyWeather organizes the world's weather data into the most valuable local information. The app includes radar, satellite, detailed wind, rain, tide, swell and UV forecasts, as well as moon phases, and sunrise and sunset times. Going beyond the average weather service, we process and fine-tune forecast data to the specific coordinates of thousands of locations including all suburbs, towns, beaches, rivers, parks, lakes and islands. WEATHER DATA • WEATHER - Six-day NOAA weather forecasts tailored to each location including min/max temperatures, and detailed weather descriptions. • RADAR - Raw NOAA radar data, refined, processed and integrated with iOS maps. • SATELLITE - National satellite view, displaying cloud cover for the entire US, integrated with iOS maps. • TIDES - The most comprehensive tide times system in the USA, bringing together NOAA standard port data with offsets generated for specific locations by WillyWeather. Includes every beach in the US, and many river systems and inlets. • WIND -The most accurate global wind forecast model gathered from NOAA, interpolated to the exact coordinates for each location, and vetted against real-time wind observations to deliver the best performing information. • UV - Hourly UV index forecasts, including alerts outlining extreme conditions when there is risk of harm from unprotected sun exposure. • MOON PHASES - Full moon and new moon phases, illumination and rise and set times. Deeply integrated with tidal data. • RAINFALL - Intuitive visual indication of rainfall probability for the week ahead. • SWELL - Swell height, period and direction for each beach and surf spot in the USA. • SUNRISE SUNSET - Sunrise and sunset times with first light and last light. • REAL TIME observational data - with trends for all locations including current temperature, feels-like temperature, rain today, rain last hour, humidity, pressure, wind speed, wind direction, wind gusts and dew point. • NOAA WARNINGS - Easily accessible and specifically targeted to the locations affected. FEATURES • Interactive rainfall radar, using iOS maps: pan and zoom like you've always wanted through the national NOAA radar network, to see exactly where rain is falling around you, or your favorite locations. Our mapping features provide more control and detail than any other US weather resource. • Stunning, interactive tide, swell, and wind forecast graphs which allow you to easily interpret the conditions at your favorite surf beach, secret fishing spot or upcoming hike - in real-time, and up to seven days in the future. We're particularly proud of our graphs, we pushed the boundaries to provide you with more context, and more detail for each weather type. • A beautiful, simple and organized interface in which the weather data that is important to you is easy to find, consume, and interact with. Our goal was to present accurate and relevant weather information to you, as quickly, and easily as possible. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
