To assist in alerting Israelis to the presence of the siren, the app developer Kobi Snir designed the free Tzeva Adom (Hebrew) smartphone app. The app allows users to select a location where they’d like to be alerted for Code Red, and even to customize the sound of the alarm signaling an impending rocket.

This app will prove especially helpful for jittery Israelis who may find themselves mistaking other sirens – such as ambulance and police sirens that have been ringing with increased frequency lately – for an air raid siren. This is also especially helpful for those who are hearing impaired, wearing headphones, or for whatever reason miss the admittedly powerful siren.
