☀☀☀☀ Lookout offers comprehensive mobile security. It primarily protects phones from malicious software, but also locates missing devices via an alarm and text system. Working with Apple or Android phones, Lookout backs up your contacts and monitors suspicious phone activity. The paid version ($2.99/month or $29.99/year) seems worthy of its cost: it includes photo security and Theft Alert emails even when a SIM card is removed. Journalists with their lives (and their work) in their phones can protect themselves against everything from losing their phone at a big news event to blocking cyberattacks with this app. — Emily Taylor
