Facebook launched a new social app for couples called "Tuned" that allows partners to chat, share photos, music and have a timeline of shared memories between them.
The app is currently available only on Apple's App Store in the United States and Canada, according to data from industry site Sensor Tower.
According to Reuters, a small team, known as Facebook's New Product Experimentation (NPE) team responsible for developing new interfaces, created Tuned.
NPE describes the app as "a private space where you and your significant other can just be yourselves."
Tuned is currently ranked No. 872 in the United States and No. 550 in Canada in the social networking category, Sensor Tower said.
In February, Facebook promised to launch a new website called "Facebook Dating" in Europe to attract young web lovers and compete other dating apps such as "Tinder".
Julien Pillot, a researcher and lecturer at leading French business school Inseec, said: "From social networks to dating sites is just a step which does not require enormous technological investment."
Pillot said: "Facebook has copied everything which worked well on other applications and added two or three functionalities. What interests them is getting users to link in the sharing of private content."
Until now, all the players in this market are too busy catching up with Match Group, the internet giant that dominates the field.
Match Group Head Amanda W. Ginsberg said her firm "will not underestimate" Facebook's potential to corner the market.
Given the numbers already on Facebook's platform and ease of access, she asked: "Why don't people try it?"
But for now we don't see any consequence for any of our brands," Ginsberg said noting that the use of several apps at the same time is growing.
For her part, Clementine Lalande, co-founder of French dating app Once seeking to attract French users with a remarkable selectivity, said "Facebook Dating's primary results are not impressive."
