Rocket attack signals
As well as the traditional sirens and radio warnings, Israeli civilians have also been receiving their alerts of missile attacks, from an app. "Color Red", which is available on iPhones and Androids, notifies users every time there is a rocket attack from Gaza.
The app was developed by young Israeli developer Kobi Snir prior to the current crisis. It can be used by residents in troubled areas who are worried about missing an air raid warning, but is also popular with those in other parts of the country who want to keep tabs on relatives. In addition, Israelis abroad are now using novelty app Yo to receive "Color Red" notifications.

Another app available is "Secure Spaces", which informs users of the location of their nearest public bomb shelter. The app is compatible with iPhone, iPad, and iPod and can locate protected areas in the Israeli cities of Ashdod, Ashkelon and Be'er Sheva.
"The use of messaging apps for public alert systems is reflection of the wider change in the mobile industry and a sign of the scale and engagement that messaging apps now have," Jack Kent, principal analyst for mobile at HIS Technology, told CNBC via email.
"With an engaged user bases of hundreds of millions of global users, messaging apps can be a very efficient and immediate way to reach users."
