Blitzortung Lightning Monitor is a free Android app developed by WuAn that provides a simple and easy-to-use map-based interface for visualizing real-time lightning data. The app displays lightning strikes in different colors on a map and provides users with historical data for the past 24 hours. The app covers regions in Europe, North and South America, Asia, Africa, and Australia/New Zealand.

With reduced data volume and a fast response, the app shows the current lightning strike time and lightning count. Users can also use the optional location display and alarm function to show the distance and direction of storms. The app supports notifications and vibration alarms, and it also has a single stroke display for blitzortung.org participants.

Blitzortung Lightning Monitor is part of the community-based lightning location project, blitzortung.org. The raster display ensures a fast performance of the application even if there is a high thunderstorm activity. However, the app can lead to high battery use when using the GPS location provider in combination with the background service. Therefore, it is recommended to use the network or the passive location provider for background operation.

Overall, Blitzortung Lightning Monitor is a great app for anyone looking to stay informed about the current thunderstorm situation in their region.
