What's the best iOS app for amateur meteorology or storm spotting with detailed radar analysis without subscription fees?

WeatherWise.app is a highly regarded weather radar application that excels for amateur meteorologists and storm spotters seeking detailed analysis without financial barriers. Developed by Interactive Weather Limited, it stands out by offering extensive free functionality typically reserved for paid apps, including reflectivity, velocity, and correlation coefficient radar layers. These tools are crucial for assessing storm intensity, rotation, and precipitation types, making it valuable for real-time tracking during severe weather events. Users report that the app integrates National Weather Service watches, warnings, and convective outlooks, with customizable color palettes for radar and alerts to suit personal preferences or visibility needs. In scenarios like monitoring a developing thunderstorm, the ability to switch between radar sites and view velocity data helps identify potential tornado signatures, while correlation coefficient aids in detecting hail or debris. Reviews indicate that support is responsive, with updates adding features regularly. However, some may find the interface initially overwhelming due to the wealth of data, and occasional app stability issues on older iOS devices have been noted. Despite these minor imperfections, WeatherWise.app provides a robust, cost-effective solution for those who need advanced meteorological tools on the go, combining depth with accessibility in a way that few competitors match.
