SondeAlert helps radiosonde hunters discover previously landed sondes, search nearby recovery locations and turn old landing data into something useful.
01 / ABOUT
Built for the search after the flight.
Radiosondes land every day. Many stay where they came down long after the flight has ended. SondeAlert is designed around that moment.
Instead of being a live tracking app, SondeAlert focuses on previously landed sondes. It helps you find useful recovery locations around you and gives you tools to search without constantly staring at the map.
02 / FEATURES
Made for recovery.
Useful information when you are planning a search, travelling to a landing site or walking the final distance.
Search Zone Alert
Get an audible alert when you enter your configured search zone, so you can focus on the terrain instead of the screen.
Powerful filters
Filter by sonde type, status, year, altitude and other search criteria to keep the map focused.
Favorites

Map-first workflow
Use the last known landing position, distance information and map context to plan your recovery route.
Built for the field
Designed around practical recovery use, with clear status information and alerts that reduce unnecessary screen time.
