Phone calls might soon be going extinct, at least if an app called Marco Polo has anything to do with it.
Video of the Day
Marco Polo is a wildly popular "video walkie talkie" app that lets you send video messages back and forth with your friends and family. It's kind of like texting, except with videos.
The videos have a Snapchat vibe, where you simply hold down the screen to create messages that are a few seconds long. But unlike Snapchat, the videos are saved in a timeline so you can have an ongoing conversation with one person or a group of people. (Yep, you can video chat with your whole family if you want to.)
To get started, you'll be asked to give the app access to your contacts. You'll then see a list of your friends who already use Marco Polo. You can start a chat by clicking on a person or inviting someone to join. There are filters and voice changers to use, and you can type messages and doodle on the videos.
