Stalqer: a new app to meet all your friend/frienemy stalking needs pretty much does what it says it does, stalks your and your friends’ locations actively and passively even if the app isn’t open. Stalqer gets around the background processing issue by setting up an email account for each user and actively pinging it (like the built in mail application) every few minutes or so. Stalqer pulls location via IP address and plops it on a map. Viola, instant creep…

One subtle but very nice feature they are implementing is the ability to tweak your notifications to selectively broadcast. Users can send messages to all friends, to all friends in a geographic vicinity (i.e. friends within a .5 mile radius) or only to specific friends. Stalqer also allows users to create custom lists and select which lists to broadcast to. This could be your co-workers for after work happy hour, to friends if you are out on the town, or to family if you are shopping for the Thanksgiving turkey.

It is interesting that they did not include a social gaming/reputation system to encourage users to achieve… This is something that Foursquare does well. Who doesn’t like to show off that “Bender” badge after 4 nights in a row of bodily abuse.

Add this to Loopt, Gowalla, Booyah Society and a new comer Rummble and we got ourselves a rummmmble in the social location junnnnngle. Booyah!
