<p>Called <a href="https://itunes.apple.com/us/app/zello-walkie-talkie/id508231856?mt=8" target="_blank" rel="noopener noreferrer">Zello</a>, the app lets you use your phone as a walkie-talkie or two-way radio as long as you have a network or WiFi connection. Users can join channels and instantly send voice messages or photos, and the app even works over older 2G networks.</p>
<p>Zello is at the <a href="http://www.businessinsider.com/zello-walkie-talkie-tops-app-store-ahead-hurricane-irma-2017-9" target="_blank" rel="noopener noreferrer">top of the App Store's free-apps chart</a>, and downloads have spiked twice in the past two weeks â during Hurricane Harvey and again on Wednesday as Irma became a Category 5 hurricane.</p>
<p>The app's popularity may have been influenced by viral Facebook and Twitter posts that said it would still work even without cell service, <a href="https://www.washingtonpost.com/news/the-intersect/wp/2017/09/06/irma-is-not-a-category-6-hurricane-a-running-list-of-viral-hoaxes-about-the-storm/?utm_term=.fdd0e507b363" target="_blank" rel="noopener noreferrer">The Washington Post reported</a>. But those posts were incorrect â if cell towers are wiped out in the storm and WiFi goes down, the app will <em>not</em> work.</p>
<p>But if you have cell service â even a 2G or 3G connection â the app could help in the event of an emergency. Here's how it works.</p>
