Sight on Scene 对比 Heads Up Community 的使用情况和统计数据

Unified alerts notification system. The app allows users to directly receive important information, via Apple's Push Notification Service, that has been input by trusted delegates from an area's authorized personnel. Ranging from more common scenarios such as accidents on the highway or school closings to severe incidents like the previous "derecho" storm - Heads Up aims to keep the public safer and more informed with live information from trusted sources. We do not require any personal information such as email or phone number. We also do not use geolocation or geofencing as to be very cognizant of your battery life. If Heads Up! Community is not in your area, please let your officials know you'd like for them to use it!
