See How Foursquare's Recommendation Engine Works

Foursquare launched an update to its iPhone and Android apps last night that includes a new recommendation engine and easier way for venues to promote specials at their location.

The recommendation feature mines the check in history of you and your friends to find similar venues you may enjoy.

You'll also be able to see tips your friends left at that venue to help make your decision easier. It's very similar to the way Facebook has started making recommendations for websites: it finds places your friends enjoy instead of relying solely on an algorithm.

We tested out Foursquare's new features today. You can get the update for free on iPhone and Android.

Here's the Foursquare icon. Tap to open the app.

Tap "Sign Up" if you don't have a Foursquare account. Tap "Log In" if you do.

HUGE: Foursquare Revamps Its App, Adding Recommendation Feature

Foursquare just announced a massive revamp of its Android and iPhone apps and it looks very intriguing.

The biggest change is a new section called, "explore," which will give Foursquare users recommendations on what to do. CEO Dennis Crowley explains the new feature:

The suggestions are based on a little bit of everything – the places you’ve been, the places your friends have visited, your loyalty to your favorite places, the categories and types of places you gravitate towards, what’s popular with other users, the day of the week, places with great tips, the time of day, and so on. We’ll even tell you why we think you should visit a certain place (e.g. popular with friends, similar to your favorite spots). You’ll find it’s helpful for general things like “food”, “coffee”, “nightlife” (we built in quick access to these searches) and you’ll be surprised by what you get when searching for really specific things, like “80s music,” “fireplaces,” “pancakes,” “bratwurst,” and “romantic.” The more random you get, the more interesting the results get (though be patient with this first release… sometimes we can’t find every random thing).

This has the potential to be huge for Foursquare. First off, it's just good for users to know where they can go. Second, just like Google search, it creates a massive advertising opportunity. Restaurants, bars, whatever, can target search results and serve up ads and offers right in the app.

Foursquare also tweaked its leaderboard and its offers for checkins. The leaderboard update allows people to get more points for different kinds of checkins. Foursquare is now serving up specials to "swarms, groups of friends, regulars, newbies, Mayors, or simply to everyone," says Crowley. He also says there will be a new notification system for those offers.
