RainVis vs Aurora Expert

RainVis turns detailed weather data into a visual forecast you can understand at a glance. Build your own forecast by choosing the details that matter most to you. Instead of jumping between separate hourly, daily, wind, rain, tide, and radar screens, RainVis lets you customize the forecast view around your plans. Track rain chance, accumulation, temperature, wind, gusts, humidity, pressure, dew point, cloud cover, tide height, tidal coefficient, and solunar timing in one visual forecast. Expand any day to inspect the hourly chart, compare multiple metrics together, and see when conditions line up. RainVis is especially useful for coastal fishing, boating, surfing, and outdoor planning, where the best window often depends on more than one number. Add tide and solunar details to your forecast to see tide movement, coefficient, moon timing, and major/minor activity periods alongside weather. Features: - Build-your-own forecast with customizable metrics - Compact daily forecast cards with visual hourly previews - Expandable hourly charts for rain, temperature, wind, gusts, humidity, pressure, dew point, cloud cover, tide, and solunar data - Coastal planning tools with tide height, tidal coefficient, NOAA tide source labels, moon data, and solunar activity periods - Rain-focused forecast showing chance, amount, timing, and accumulation - Current conditions for searched cities, saved places, or your current location - Radar with recent NEXRAD reflectivity history - iOS widgets for quick glanceable forecasts - Optional RainVis account for syncing Pro access across devices RainVis works immediately without signup. Free users can view the core visual forecast experience. RainVis Pro unlocks deeper planning features, including 15-day forecast trends, extended hourly forecast charts, longer radar history where available, live activities, and account-based access across iOS and web. Weather forecasts and coastal conditions can change quickly. Always follow official alerts and emergency guidance from the National Weather Service, NOAA, and local authorities.
