Here's how to use Marco Polo, the video messaging app that could replace Snapchat one day

If you've ever wanted to recapture the magic of playing with walkie talkies as a kid, there's an app designed to do just that - 2017-style. 

Marco Polo bills itself as the "video walkie talkie," a video chat app that lets you send quick messages back and forth with your friends. 

Much like Snapchat, Marco Polo traffics in messages that are only a few seconds long. Unlike Snapchat, however, the app saves your videos so you can have a running conversation with your friend or a group of friends.

Marco Polo was created by a company called Joya Communications, which says on its website that its mission is "to help people feel close no matter the distance, enabling people to remain connected in convenient and meaningful ways."

The app has been around for more than a year, but is starting to catch on: It has a 4.4 rating on the Google Play Store (out of 5) and more than 84,000 reviews, and a 4.5 out of 5 on Apple's App Store. Marco Polo is also the eighth top free social networking app in the App Store.

And a quick Twitter search pulls up hundreds of tweets about the app. Some users complain about Marco Polo spamming their contacts - the app does ask to access your contacts during the set up, but it apparently has texted some users contacts in the past - but most tweets look a lot like this one:

Most users also mention using the app to communicate with their families - which means Marco Polo isn't just for teens.
