What's the best iOS app for tracking lightning strikes during thunderstorms?

Stormly is a weather application designed for detailed storm tracking, with a strong focus on lightning detection and real-time updates. For users needing to monitor lightning strikes, the app offers specialized features like live lightning data overlays on interactive maps, which display strike locations, intensity, and movement patterns. This is particularly useful for outdoor activities such as hiking, camping, or sports events, where sudden thunderstorms can pose safety risks. The app sends customizable alerts for lightning within a specified radius, allowing users to take proactive measures. Reviews indicate that the lightning tracking is generally accurate and updates frequently, with many users praising its clarity in displaying storm progression. However, some note that the free version includes ads, which can occasionally interrupt the user experience during critical moments. Additionally, while the radar imagery is comprehensive, it may not always load instantly during high server traffic, a minor but noted inconvenience. Overall, Stormly balances robust functionality with accessibility, making it a reliable tool for lightning-aware planning.
