After facebook this is best app for social networking, I am really like this app, this app is simple and easy to operate, we just need to save our contacts and connect with other friends, this app consume very less amount of data , I used to recharge with 10 mb of data which is sufficient for whole day for operating this app.
This app does not use any advertisement and available for 6 month subscription free of cost, my friend is really addictive for this app, best of luck for whats up team.
