Facebook Moments is shutting down after almost four years.

The app, which was first launched back in 2015, gave users the ability to manage pictures uploaded and identify individuals in them via facial recognition.

This was useful for tagging friends and family in groups of photos that would otherwise take time to tag specifically. Facebook will be stopping development and support of the app on February 25th.

Part of the issue with Moments was how the app did not properly link photos to Facebook itself, but instead kept things somewhat separate. Most users would instead just share photos on Facebook. To help with the transition, Facebook created a tool to help users save their photos that were made from Moments, which could be put into a private album, on their Facebook page, or by saving to a device.

After the discontinuation of Moments, Facebook users will have till May to save their photos from the app before they’re gone forever.
