Google Latitude is a location-based mobile application that allows user to share his or her location with selected friends. The search engine has gone further besides sharing the location, but also letting you check-in to places and get special statuses.
Location-based mobile applications are getting popular, seeing how six million users are on foursquare since its launch in 2009. Well, Google has also launched their beta location-based app that year, called Google Latitude. And the company has recently announced that Google users can now check-in on Latitude, and lets you do more than just that such as adding context such as captions to pictures.
You can also turn on check-in notifications in Latitude’s settings and get a notification to check in at a nearby place once you arrive; choose to automatic check-in to locations you have designated so that you’ll be checked-in when you reached; and automatic check-out when you leave your location. On top of that, you can also choose to check in at favorite places to earn special status there including becoming a “Regular”, “VIP” or a “Guru” on its Place page. (Similar to how you earn badges on foursquare).
You can start checking in with the download of the latest Google Maps from Android Market, or if you are using the iPhone, download the latest Latitude app for iPhone.
