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.

Live weather radar, nowcast and rain alerts, hyperlocal forecast and hurricane tracker, built to help you see, understand, and act on rain before it changes. Tracking a hurricane’s path or just checking if it’s dry enough for a walk? RainViewer shows the actual rain on the map. Data reaches your screen in seconds, direct from the radar source, not a third-party feed. 10 million downloads. RAIN FIRST We rearranged the forecast tab to put nowcast and radar at the top. The minute-by-minute rain intensity chart shows when rain starts, peaks, and stops, with a radar map preview and temperature beside it. Cleaner hourly and daily charts now show rainfall totals. The chance of rain is only half the picture: how much falls, and how fast, makes the difference. BUILT FOR IPHONE DUO RainViewer adapts radar map to every pose in Duo: open it and your locations sit beside the forecast on the inner display, with more hours and days at once; close it and the forecast follows you to the outer display; in landscape, navigation moves to the side and the rain stays in focus. THE RADAR MAP YOU ACTUALLY USE • 2-hour rain nowcast updated every 10 minutes. • Tap the map to see rain details on every layer. • Fullscreen mode clears the interface for clean screenshots and storm animations. • 48-hour radar animation. • 60fps vector map with arrows that show rain direction. • Coverage in 80+ countries across the Americas, Europe, Asia, and Oceania. HOURLY AND 14-DAY FORECAST Temperature, conditions, wind speed and direction, chance of precipitation, and rain amount hour by hour for 72 hours and day by day for 14 days. RAINFALL TOTALS (QPE) Pick a window - 1, 3, 12, 24, or 48 hours - and tap any spot on the map for the exact amount in millimeters or inches. RADAR SCAN AGE Tap the map to see when each area was last scanned, so you know when to leave. RAIN ALERTS YOU CAN RELY ON Set custom alerts for your locations. Get national severe weather alerts from the US, most of Europe, Thailand, Saudi Arabia, and more. HURRICANE AND STORM TRACKER Follow hurricanes, typhoons, and cyclones on the map. See each storm's live position, path, category, and wind speed in your units AI WEATHER INSIGHTS Get AI to write a short summary of what to expect. APPLE WATCH (FREE) Standalone app with radar map, satellite, forecast, severe alerts, and complications. Works without your iPhone. WIDGETS AND LIVE ACTIVITIES Radar and minute-by-minute rain widgets for Home Screen and Lock Screen. Live Activities show rain intensity as it changes. PRO RADAR (US + MOST OF EUROPE, 22 COUNTRIES) Doppler products on all tilts - reflectivity, velocity, spectrum width, and the differential measurements used by meteorologists.

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.
