There was a time when Twitter was the second biggest social network platform behind Facebook. But in the years following its inception, the microblogging site has been overtaken in the charts by its competitor’s apps: Messenger, Instagram, and WhatsApp.

A couple of months ago, Twitter decided to reclassify itself as a ‘News’ app in the iOS charts. The move from the ‘Social Networking’ section meant it became the number one application in its category, and no longer had to compete for visibility against the likes of Instagram and Pinterest.

Identifying itself as a news app was probably a good move by the company, as Twitter’s number of daily users has just been surpassed by yet another messaging app: Snapchat. The four-year-old service now sees 150 million active users every day, whereas Twitter has an estimated 136 million daily users, according to Bloomberg.

Twitter doesn’t reveal exactly how people use its services each day, so Bloomberg worked out the figure from Twitter’s publicly announced 310 million monthly active users and the estimated percentage of how many use the service daily (44 percent).

At this week’s Code Conference, Twitter CEO Jack Dorsey acknowledged Snapchat’s popularity among younger audiences, calling it “very modern.” He admitted that part of the reason why Twitter struggles to attract new users is because they can find the service confusing and alienating.

Twitter is continuing to introduce changes in the hope that it will make the service seem less intimidating to newbies. Over the coming months, names, photos, GIFs, Videos, polls and quote tweets will no longer count toward the 140-character limit - a restriction that could eventually increase or even be removed.
