Facebook is shutting down Moves, Hello, and tbh, a trio of apps it launched or acquired over the last four years that haven’t developed large audiences. Facebook says it’s shutting down all three due to “low usage” and that it will delete all of their user data within 90 days.

In the case of Moves, a stylish fitness tracking app launched in 2013 and bought by Facebook a year later, and Hello, an Android dialer that merged Facebook details with contact info, the issue wasn’t just a lack of audience but a lack of development. Neither app saw much improvement after launch and neither has been updated in more than a year. Hello only seemed to make it four months before being abandoned.
