Combine Facebook and twitter and Google Latitude. You have aka-aki.
Operated by a Berlin, Germany based company, aka-aki is an online community that puts social networking on the street. That’s why aka-aki does not only consist of this community website but also includes a mobile phone application. Using the GSM, Wi-Fi or GPS information which ever is available, the aka-aki mobile phone application shows you details about people belonging to your circle. In the city, in the region or up to 50km away. For instance, when other aka-aki members are there, your mobile phone will show you a photo, mutual friends etc.. Even other functions associated with an online community like writing messages, saving friends, etc. will work while you’re on your way using the aka-aki mobile phone application.
Going into some details, aka-aki shows you on your mobile phone the profiles of people in your circle. You also see which friends in the community are online at that moment and may exchange mails with other members. You can also use aka-aki to show people around you, who you are and what you like by adding stickers to your profile. You can create and maintain your profile at the aka-aki community website. There you may also check whom you recently met while out and about, since aka-aki logs the encounters. And probably more of things still to come.
Installing it on the iPhone is a straightforward task as the application is available from the App Store. Some quick information and your account is created.
While the application is obviously big fun to use, who knows what can be done with it and the stored information especially when in wrong hands? Google Latitude raised some scepticism, why should it be different for aka-aki? Not sure I really want to use it.
