Facebook quietly launched an app that lets couples chat together.

It's called Tuned, and it's meant to let partners exchange messages, music and build a digital scrapbook. Tuned was created by Facebook's NPE division which launched in 2019.

The team behind the free app focuses on inventing new ways for to interact. The team's experimental services will "change very rapidly and will be shut down if we learn that they're not useful to people," Facebook said in a blog post.

According to its description, Tuned is billed as "a for couples" though it doesn't mention end-to-end encryption like WhatsApp. Tuned is only available in the App Store. It has 3.2 out of 5 stars.

Users must be 13 or older, Facebook said.

The world's largest social networking app first entered the courting space in 2019 with the launch of a dating section on the app. Users have to opt-in to create a profile and they swipe through potential matches who have also signed up.

Facebook Dating is baked into the main Facebook app people already use.
