How many times have you asked a friend to call your phone because you can’t find it? Whether it slipped behind a couch cushion or was left in a jacket pocket, there are plenty of hiding spaces that phones love to hide in. Thanks to a new app called Marco Polo, however, finding your phone just got a lot easier – and more fun. Available for the iPhone, iPad and iPod Touch, Marco Polo lets you find your device by yelling for it. Just like at the pool, shout “Marco!” and your device will respond with “Polo!” The app runs silently in the background until you need it, and can be customized with 30 different voice options. You can even change the input phrase to whatever words you want to shout. Marco Polo isn’t the most important app you can download to your iDevice, but it’s practical – and even a little fun. If you seem to always be losing your phone, you can download Marco Polo in the App Store for 99 cents today.
