If you enjoy checking in at different places while you're out, you probably use Foursquare fairly religiously. They've been been on a roll lately, introducing a ton of cool new features for their mobile apps. Yesterday, they updated their iOS app to support the iPhone 5 and iOS 6. On top of that, users now get more personalization options and a more tailored search experience.
The biggest improvement Foursquare made to the user interface is the slight redesign of the Explore tab. It now has a simpler design and even more search options. Because Foursquare knows what you and your friends like and knows what’s popular in the neighborhood, they can provide you with tailored suggestions instead of seeing a bunch of random search results.
They have also added new search categories that are personalized. Foursquare can provide top picks or show only places that have Foursquare specials. You can also easily access places that you've saved. Moreso, the app can show you places that you haven't been to yet or even only places that you've been to or your friends have been to.
Foursquare for iOS is a free download and the update is available now in the iTunes App Store. A recent update does appear to be available on Android as well, but it doesn't look like the new personalization features have hit yet, but we can only guess it'll be a matter of time.
