MSQRD is a face-filtering app for iOS and Android users, and was acquired by Facebook in 2016. It helped boost Facebook's AR image and video tools, and was pitted against Snapchat's AR filters. Post-acquisition, Facebook promised that the AR app will remain a standalone app and would provide updates, but stopped doing so by the end of 2016.
Eventually, with Instagram launching its own AR filters on Instagram, and Snapchat regaining traction, it made no sense for Facebook to maintain the app.
