Twitter Inc (NYSE:TWTR) has deployed a new feature to allow users to see tweets from a specific place like a sports stadium, business place or music festival. Foursquare is powering precise place identification for this new feature. In exchange, it will receive links back, prominent branding and the ability to improve its own database, reports TechCrunch.

Only for iOS users

Twitter’s new location feature is available only to iOS users and will go to other platforms such as Android later.

Foursquare CEO Jeff Glueck said, “We’re excited about this integration which has been getting deeper over time. Location can provide important context for any moment, and our location intelligence is best-in-class. We’re proud to support Twitter in the US, Canada, Brazil and many other geographies. Stay tuned for more to come.”

Twitter’s new feature will be visible in the main timeline when a user tags a specific location which is powered by Foursquare. TechCrunch explains that a user will be brought to a location feed with a map up top if he/she clicks through to the tweet detail and then clicks the location. There the user will see a tab of tweets from that city or place with the option to check the tab dedicated to media such as a photo from there.

The city-level location, which many users leave on all the time, is not shown on tweets in the main profile or timeline. Uusers have to click into a tweet’s detail view to see it and click on the city name to see its feed.

To help Twitter with ad data

In late 2014, Business Insider reported that Twitter and Foursquare would strike a partnership. In March 2015, the companies officially announced the deal and previewed a prototype of the feature. However, the specific location tags are appearing in the timeline only now, almost 15 months later.

According to the micro-blogging site, a basic version of location feeds was available before also, but it was not possible to tell if a tweet was tagged with a location without opening the detailed view. The location feeds linked to the tags could encourage people to tweet more while traveling, thus improving Twitter’s ad targeting data.

On Friday, Twitter shares closed down 3.52% at $16.44. Year to date, the stock is down by over 36%, while in the last year, it is down by over 53%. The stock has a 52-week high of $38.82 and a 52-week low of $13.73.
