This may have to do with reddit content being longer and more engaging—which lends itself to a better experience on desktop—than the quicker, more digestible updates found on Facebook and Twitter. Still, our estimates show that reddit's mobile user base will continue its double-digit growth through 2021.
“reddit has a huge opportunity here—continued investment in their mobile platform could lead to a much wider audience and help close the gap with Twitter and Facebook,” said Nazmul Islam, junior forecasting analyst at eMarketer.
reddit released its mobile app in 2016, which has made the platform more accessible to younger consumers who are accustomed to using social media on their smartphones. The company has been continuously updating its app with additional functionality, and, taking a cue from competitors like YouTube and Twitch, reddit began beta testing livestreaming on its app this summer.
