11月3日的Повітряна тривога (Air Alert)应用程序分析

Повітряна тривога (Ukrainian for "air raid alert") brings Ukraine's air raid alerts to you. Every air raid alert issued in Ukraine appears in the app in near real time, with a delay of at most one minute. It does not appear on a distant map, but on yours: each affected area lies exactly as far from your location, and in the same direction, as it really lies from Kyiv. THE ALERT IS REAL. ONLY THE MAP IS YOURS. • Two maps: your surroundings with the transferred alerts, and the geographically correct map of Ukraine • The colour shows the type of alert: air raid, artillery shelling, urban fighting, chemical or nuclear threat • The size shows the age: fresh alerts pulse, older ones get smaller and paler over 30 days • Glowing regions show where alerts were most frequent in the last 30 days • Optional notifications for every new alert, also limited to a radius of 50, 100 or 200 km • Background on the war, on air defence and on where the data comes from The data are the official Ukrainian air raid alerts, provided by the volunteer project alerts.in.ua. They go down to the level of individual raions and communities. Повітряна тривога is an artistic awareness project and not a warning app. If you are in Ukraine, please rely exclusively on the official warning channels. No ads, no tracking, no sign-up. Your location never leaves your device. Available in German, English, Ukrainian, French, Spanish, Turkish, Polish, Hebrew, Arabic, Italian, Dutch and Portuguese.
