Although Flickr was one of the first web services to utilize tags to aide user's search keywords, the iOS app has upgraded from 'tags' to 'hashtags' to enhance search capabilities.
The update should allow users to find photos easier and couple the search terms in a closer relation than before. Much like its alternative services to adopt the hashtag, they can be used for search query's but also added to a photo's title or description.
The news comes following recent rumours circulating Facebook taking on the hashtag functionality. It also follows Flickr's adoption of retro filters and (@)usernames.
Users have embraced hashtags on the app for years but Flickr has finally updated its service to support the feature.
The revamp will only function on the iOS version of the app with Flickr's website and Android variants remaining on the old system of 'tags'.
To mark the new update, Flickr have begun a #FlickrFriday competition, allowing users to have their submission(s) featured on the FlickrBlog.
