In the age where Hamas and the IDF trade not only projectiles, but barbs on Twitter, technology is taking on a new role in how people deal with security threats.The Color Red siren, in particular, is a crucial safety warning for Israelis, alerting them to incoming rockets and warning them to get to shelters.But for those who cannot hear, are out of auditory range or want to keep abreast of where else rocket- warning alarms are sounding, Ari Sprung and Kobi Snir developed the Red Alert smartphone application.Android and iPhone users can download the app, which sends a notification to their phone any time the siren goes off. An English-language version is now available as well.A Twitter account, @ AlarmDarom, has been automatically tweeting the same information. Those who want to forgo the app can set up a notification whenever the account Tweets.But what good is a Color Red alert if you don’t have a safe place to get to? To that end, App-maker iApp created Secure Spaces, which helps users find the nearest public bomb shelter so they can get to safety even if they are far from home. Unfortunately, it only has information for Ashdod, Ashkelon and Beersheba.Tel Avivians who are looking for the public shelters can find them through the municipality’s app, or its websites.Jerusalem’s municipal website offers a list of shelters.
