I’ve downloaded the iPhone app WhosHere a long time ago and while I find it a robust iPhone app, I can’t find useful because not all iPhone users in the part of the world where I am located will bother to download it on their iPhone. You see, WhosHere is a proximity social app. So you need to find other iPhone users with the app to use it. The app locates potential dates or network based on a series of questions about yourself and your interest. It then finds matches in the proximity of the area where you are located. And when you find someone interesting you can then send free text and images to them, receive free calls and now with WhosHere 2.0, call them as well.
