To be honest, I installed that app. But I couldn't go beyond that because it was asking for the PIN number it sent to my very old contact number. I gave my then phone number in the form(2 years ago), and it was asking for the PIN. I was fed up and with my current schedule, I can't go and change my phone number so that I could have access to this app.
May be they should think of some other way to connect the users. That would be damn helpful.
