Rainbow AI

Rainbow Weather is a mobile app that uses AI and machine learning to deliver hyper-accurate, minute-by-minute precipitation forecasts. You open the app, see a live radar map of rain in your area, and get predictions up to four hours ahead. It updates every ten minutes, so you always know when that next shower is coming. No more guessing whether you need an umbrella — the app tells you exactly when rain will start and stop at your location.

The app stands out because of its precision. It combines data from satellites and ground radars with AI models to generate forecasts at a 1x1 km resolution, updated every minute. That means the forecast for your block might differ from the one a mile away. Features include a precipitation forecast layer, cloud cover, and a global forecast mode. You also get seven-day weather, UV index, dark mode, widgets, and push notifications for weather alerts. A recent independent ranking by WeatherIndex.ai named Rainbow the most accurate short-term precipitation forecaster globally.

Rainbow Weather is useful for anyone who spends time outdoors — commuters, runners, cyclists, gardeners, or event planners. It also offers industry solutions for logistics, agriculture, energy, and more via its API. The app is free to download on iOS and Android. If you need weather data for your business, Rainbow provides an API with enterprise options.
