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.

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.

View Canadian weather radar, satellite imagery, GFA, and surface analysis charts. --- Radar Map ---- View radar animations for all of North America (including Alaska & Hawaii) and choose between Precipitation Rate imagery (calibrated for either rain or snow) or Precipitation Type imagery (shows the type of precipitation as rain, snow, mixed, etc). Customize animation speed, delay, radar opacity, and map type. *Note: Precipitation Type imagery is currently experimental and may not accurately reflect the exact type of precipitation falling in your area. --- Radar Images --- Select from a list of 31 stations nationwide and animate up to 100 images calibrated for either rain or snow. Visit the Environment Canada website for a detailed map of radar coverage in your area. *Note: Fort McMurray is not included since the overlay images were never produced by Environment Canada. Radar coverage in the Fort McMurray area is included in the Radar Map product. --- Satellite --- View satellite imagery from the GOES-19 weather satellite in visible light, infrared, and combined. Choose between the Meteorological Society of Canada (MSC) or the US National Oceanic and Atmospheric Administration (NOAA) and animate up to 6 hours of imagery. Coverage includes all of Canada and most of the USA. --- Charts --- View Surface Analysis and Graphical Area Forecast (GFA) charts for all of Canada. The Surface Analysis is a snapshot of the current pressure and frontal systems across Canada. GFAs give you a 12-hour forecast of the expected pressure and frontal systems at a regional level, along with information such as expected precipitation, cloud height & coverage, turbulence, icing, and freezing level. While these charts are typically used by pilots, they offer an excellent look at the current weather systems in a given region. Quickly switch between 0/+6/+12 GFA images and between "Clouds & Weather" and "Icing, Turbulence, & Freezing Level" images. You can also view GFA pairs side-by-side instead of having to switch between them. --- Data Providers --- Radar: Environment Canada Satellite: Meteorological Service of Canada (MSC), National Oceanic and Atmospheric Administration (NOAA), Cooperative Institute for Research in the Atmosphere (CIRA) Charts: NAV CANADA

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.
