A new app can help you find your misplaced smartphone by allowing your device to respond when you shout, giving you clues to its location.
When using the Marco Polo app, users can find their hidden device by shouting "Marco!" loudly. It will respond "Polo!," so they know where to look for it.
The input phrase can be customised by the users so they can yell out whatever they want, CNET reported.
The app was created by Matt Wiechec, a designer and developer based in Toronto.
"In those moments where we have all lost our phones to the sofa cushions, or left them on the coffee table, or in the bathroom, we now have a fun way to find them again," Wiechec said.
"It's like playing tag with your phone, just walk around shouting Marco! and your phone will ring back Polo! in another room," he added.
