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.

Combine features and design from your favorite apps.
Your first Build Kit is free with a verified email.
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.

Weather that feels alive. Weather360 turns the forecast into a living sky over your city, then tells you what it means in plain words: when rain starts and stops, what to wear, and the best hour to head out. A SKY YOU CAN READ • Real animated skies: sun, clouds, rain, snow, fog and thunderstorms, drawn for your place and time of day. • Press play to watch the next 24 hours unfold, from sunrise to moonrise, with a short written outlook for each part of the day. Plus see the same sky playout for next 10 days [7 days for non-subsribers] • Clear, friendly summaries like "Rain easing after 3 PM, grab a light jacket," written on your device. RAIN, TO THE MINUTE • See exactly when rain starts, how hard it falls and when it stops, minute by minute for the next hour. • Live radar with storm motion and your spot pinned on the map. • Wind in colour: speed-coloured streaks over a living map, with gusts at your location. ALERTS THAT MATTER • Official severe weather alerts, such as flood, wind and storm warnings, the moment they're issued, with what to do in plain language. • Rain heads-ups before it starts and when it's about to stop (Premium). • Rain in your Dynamic Island and on your Lock Screen with Live Activities (Premium). PLAN YOUR DAY • Activities: runs, rides, dog walks, hikes, gardening, stargazing and more, with every hour scored so you can pick the best time. • Morning and evening reports: your day in four moments, heads-ups and what to bring, in a story you can read in ten seconds. EVERY DETAIL, BEAUTIFULLY • Hour-by-hour and day-by-day charts for temperature, feels-like, rain, wind, humidity, UV, clouds, visibility and pressure. • Air quality, UV and pollen, with advice that helps. • Moon phases with a calendar you can drag through, plus moonrise and moonset. • Tides for your nearest coast, with the best beach time (Premium). MADE FOR EVERY SCREEN • iPhone, with a Dynamic Island that shows the rain as it comes. • iPad, with the live sky on one page and every detail on the other, plus a side rail for quick navigation, keyboard shortcuts and trackpad support. • Mac, and widgets for your Home Screen and Lock Screen. PRIVATE BY DESIGN No account needed and no tracking. Your location is only used to get your weather and send your alerts. WEATHER360 PREMIUM Go further with Premium: • Rain alerts before it starts and when it stops • Live Activities in the Dynamic Island and on the Lock Screen • The extended 10-day forecast • 12-hour radar across the US and full-day wind playback • Every activity, any time • Tides, pollen forecasts and premium widgets Premium is available as a monthly or yearly auto-renewing subscription, with a free trial for eligible new subscribers.

Hypothesis 1
Assumption to check: Inaccurate forecasts
Validate with people who use this workflow before building.
Hypothesis 2
Assumption to check: Too many ads
Validate with people who use this workflow before building.
Hypothesis 3
Assumption to check: No hyperlocal data
Validate with people who use this workflow before building.
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.
Not assessed in a Build Kit yet.
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.
