Instagram has rolled out yet another feature eerily reminiscent of an upstart social media competitor. "Dual" is a new feature launched last week on Instagram Stories and Reels that allows you to take a photo or video using both the front and back cameras simultaneously. Those with accounts on BeReal, the social media app that has soared in popularity recently, know that Dual looks very familiar. 

BeReal, which has been dubbed the “anti-Instagram” app, forces people to share the unfiltered realities of their day. Once a day at a random time, BeReal notifies users to post what they're doing by snapping a picture that shows both sides of their camera. You are given two minutes to post and once you post, you are able to see what your friends are doing during that same two minute interval. The posts disappear after each day and only you have access to your previous BeReal post history. A few days ago, BeReal reached number one on the App Store, surpassing older social media apps such as Instagram.
