Weather apps answer "what's the weather?" Nobody actually asks that. People ask: can we still do the cookout? Is the game getting rained out? Should I leave early before the snow? Weather or Not exists to answer the real question — will weather wreck your plans — in one sentence.
You tell us where you are and when your plans happen. We check the official hourly forecast for rain, snow, ice, thunderstorms, high winds, extreme heat, and bitter cold, plus every active weather alert for your area. Then you get a verdict, not a dashboard.
Our forecast data comes directly from the National Weather Service (weather.gov), the United States government's official forecasting agency — the same source most weather apps quietly rely on. We just skip the clutter between you and the answer.
Weather or Not is free, requires no account, and works on any device. If it saved your Saturday, tell a friend.
