In an unusual retooling, novelty app Yo is now being used to alert Israelis abroad of rocket attacks. According to Hebrew-language tech blog Geektime, Yo is being used to send Israelis who are living abroad notifications of rockets falling in their home country. The notifications are being conducted by Yo in conjunction with the Israeli Color Red app, an unofficial, self-described "propaganda tool" that sends push notifications of rocket explosions. Following a recent surge in Israeli-Palestinian violence, the Israeli army is currently conducted an offensive in Gaza and more than 100 rockets were fired from Gaza at Israel within the past 24 hours. The two sides are engaged in the fiercest fighting since 2012.
