RedAlert for Android


RedAlert was developed by volunteers to provide real-time rocket alerts for Israeli citizens.

The app utilizes real-time alert data provided by the Home Front Command (Pikud Haoref), which makes it extremely fast, reliable, and stable.

Note: Rocket alerts are detected using the open-source pikud-haoref-api Node.js package.
