GrayCloud

I miss Dark Sky, so I built my own weather app. Here's how GrayCloud works: * Raincast: minute-by-minute rain prediction and accumulation tracking for your exact location * Forecasts: 10 day forecasts use multiple high resolution sources and correct for bias at your location. * Alerts: rain starting, stopping, severe weather, daily summary and more * Widgets: home and lock screen widgets * Multi-platform: apple watch and mac apps I use NOAA and ECMWF models for core weather data and a custom model to compute rain accumulation and the next 60 minute radar movements. I also offer Apple WeatherKit as an alternative weather source.
