Skyhook recently announced partnerships with three different location-based social networking apps.  All three are available on Android.  While this again speaks to the need for better location on Android, it also indicates the growing popularity of location-aware social networking apps

One app Skyhook partnered with this week is LifeAware, winner of an Android Developer Challenge prize.  LifeAware helps to notify family members of your whereabouts by sending automatic alerts when a family member leaves or enters a customizable geographical zone.  Because the app ensures the safety of family members, LifeAware needed Skyhook to ensure that user location would be quickly and accurately found.

Skyhook also announced a partnership with Glympse, an app that allows users to “share your where.”  With Glympse, users can send out notifications of their whereabouts to friends over a selected period of time.  This can inform contacts when you are stuck in traffic, for example, without requiring you to mess with your phone.

Finally, ZOS Communications also added Skyhook technology onto their social networking app, Zhiing.  Similar to LifeAware and Glympse, Zhiing allows you to share your location with others by sending a text message.  The app also provides maps and turn-by-turn directions so friends can find you.

Social Networking is a leader among other location-aware app types, stemming from the fact that people like to stay in touch one another and know where their friends are.  It is likely that the popularity of this category will continue to rise as developers come up with more innovative ways for us to share location with each other.
