The Tempest Weather app, developed by WeatherFlow, functions as both a remote monitor for the proprietary Tempest hardware station and a standalone weather application. Its market position is distinct, catering to users who invest in a specific ecosystem for granular, personalized weather data rather than those seeking a generic forecast. This dual-purpose nature defines its strengths and shapes user expectations, positioning it as a specialized tool within the broader weather app category. Core functionality revolves around displaying a dense array of meteorological metrics. Users can access real-time readings for temperature, humidity, wind speed and direction, barometric pressure, UV index, solar radiation, and rainfall—all sourced directly from their installed station. The app also provides detailed forecasts, lightning strike detection alerts, and historical data charts. A significant addition, frequently noted in user feedback, is the integration of animated radar maps, which addresses a previous gap in its offering and allows for visual storm tracking. In practical use, the app excels at providing a dashboard for hyper-local conditions. For a runner checking if a passing shower is imminent or a gardener deciding whether to water, the data specificity is a key advantage. The interface is generally clean, prioritizing current conditions and forecasts, with deeper data available through taps and swipes. The recent restoration of iOS widgets is a noted improvement, allowing for at-a-glance information directly on the home screen. However, the experience is inherently tied to owning the hardware; while the app can provide forecasts for any location, its premier feature—the personal station data—is geographically fixed. User reviews consistently highlight several trends. Praise centers on the station's installation ease, data accuracy verified against professional sources, and the value of the integrated radar. Many describe it as their primary weather source. Critiques and desires for improvement are also evident. Some users report occasional bugs with location services or map errors. There is also expressed interest in broader smart home integration, such as official Google Assistant support, and more granular interface customization, though one review notes that display customization is possible with guidance from support. Overall, the Tempest Weather app is a highly effective portal for a dedicated hardware system. Its main limitation is its dependency on that hardware for its full potential. As a standalone weather app, it is competent, with good forecasts and radar, but faces stiff competition. For Tempest station owners, however, it is an indispensable companion that turns raw environmental data into actionable insight, despite minor interface quirks and integration wishes that some users express.
