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.

Read full description

IVAN Air puts real-time air quality from the Imperial Valley's community monitoring network in your pocket. See how clean — or unhealthy — the air is right now at monitors across the region, and get notified the moment the air near you takes a turn. Built on the IVAN (Identifying Violations Affecting Neighborhoods) network operated by Comité Cívico del Valle, IVAN Air brings together readings from Dylos, SLX, Trinity, and CERCA monitors into one simple, color-coded view. WHAT YOU CAN DO • List view — every monitor with its current reading, sorted so the worst air is easy to spot. Sort by nearest to you. • Map view — all monitors on a live map, with nearby ones grouped so dense areas stay readable. Tap any monitor for full details. • Monitor detail — current AQI or CAL reading, color-coded categories, and health recommendations. • Favorites — star the monitors you care about and filter the list and map to just those. • Push alerts — pick the monitors and the air-quality level that matter to you, and we'll send a notification when one reaches it, even when the app is closed. Set separate levels for AQI and CAL monitors. COLOR-CODED, AT A GLANCE Readings use the familiar EPA Air Quality Index (AQI) scale and the CAL scale, with the same green-to-maroon colors you see on official air-quality maps, so a number always means something. PRIVACY-FIRST No account required. No ads. No third-party tracking. Your location, if you allow it, is used only on your device to find nearby monitors. IVAN Air is a free, community-driven tool to help Imperial Valley residents understand and act on the air they breathe.
