Facebook's Paper app is a mystery to many users, which is essentially why the social network has announced it will shut down on July 29.

The iPhone-only news app launched in 2014 but seemingly failed to gain traction, although official numbers were never announced.

With Facebook closing down Creative Labs - Facebook's internal team that brought the app to life - in December, and Paper not seeing an update this year, the writing was on the proverbial online wall.

This message has now appeared to users when opening the app: "We know that Paper really resonated with you - the people who used it - so we've tried to take the best aspects of it and incorporate them into the main Facebook app."

Mike Matas, Facebook's product design lead for Paper, tweeted that more than a hundred thousand people still use Paper - small change in comparison to Facebook's 1.6 billion users.

The message continued: "For example, the same team that built Paper also built Instant Articles... using many of the same tools, design elements, and fundamental ideas as Paper.

"We know not all the features you love will move over to Facebook, but we hope you'll continue to notice elements from Paper improving the Facebook experience for everyone."

Paper, it's time to meet the shredder.
