"єТривога" is an iPhone application designed to provide real-time threat notifications in Ukraine. The app sends push notifications to users about threats in their chosen area or city, including air raids, missile strikes, artillery shelling, explosions, and planned explosive works. Developed by Ukrainian IT volunteers in Poland, the project operates 24/7 with the support of over 30 volunteers who ensure prompt and accurate notifications. All alerts are manually sent to users, ensuring critical information reaches them in a timely manner.

The app is not affiliated with any Ukrainian government institutions and serves as an independent source of information for users seeking to stay informed about potential dangers in their region. For those in Ukraine, "єТривога" offers a crucial tool for staying aware of security threats, thanks to the dedication of its volunteer team.
