Today Yahoo has released a completely redesigned version of Flickr for iOS — it’s first update since December 2011 — as well as its website.

Once a major player, Flickr has begun to feel outdated. Members have moved on to other photo hosting and sharing services like Facebook and Google. The company hopes that the new look and features will bring people back to the service.

The new iOS app comes with a fully integrated Twitter experience, marking another win for the social network, which recently lost support for Instagram images. It also integrates with Tumblr and Foursquare. Flickr’s mobile app also comes with 16 photo filters — which are named for animals — powered by Aviary, the same mobile software development company running Twitter’s new photo filter feature.

Other improvements include the ability to log in using your Yahoo, Facebook, or Google account credentials, a re-imagined search experience, full Groups capabilities, and a user-friendly activity log. You can download Flickr for iOS from the App Store. No date has been set for an updated Android release. now features a new “simplified” navigation bar designed to make browsing not only easier, but faster. The redesigned Explore page now sports the same look and feel of Flickr’s Contacts and Group Pool pages. Yahoo plans on rolling this out to everyone over the next few days.
