MOBILE APPS

 5 NOT SO POPULAR BEST SOCIAL APPS:::

 1. Vine (free, iOS) 

  This video app from the makers of Twitter topped the list of free iOS apps less than three months after it debuted. Vine lets users take up to 6-second videos then share them via Twitter or the app itself. The one-touch video continuation feature means you can shoot multiple scenes and incorporate all those clips into one video. Vine has a similar interface to Twitter, so you can explore other users' videos and search by topic.

2. Snapchat (free,iOS,Android)

Snapchat allows users send picture messages to friends in real-time. Photos automatically delete after a maximum of 10 seconds, which makes the free app often used for sending silly (or risque) shots. Be careful, though: Users can take screenshots of your shots, but you'll receive a notification if a screen has been grabbed.

3. Foursquare (free,iOS,Android,Windows Phone,Blackberry 10)

Foursquare is a location-based app that tells you what's nearby based on what others suggested. When you're at a location, you can check in and potentially score tips and deals, and with every check-in the app gets more personalized and gets better at recommending places it thinks you'll like. Search for what you're looking for or browse what's near you, then Foursquare gives you directions, hours, menus and photos so you can decide on a destination. Plus, become mayor of a location and get bragging rights over your friends.

4. Pinterest (free,Android,iOS,Blackberry 10)

For those obsessed with pinning everything from recipes to home ideas to humorous quotes, the Pinterest app lets you pin from anywhere. Search, browse by category or rediscover things you've already pinned from the free Android, BlackBerry 10 or iOS mobile versions.

5. Spotify (free,Android,iOS,Windows Phone)

Not only does Spotify let you listen to your favorite tracks and discover new music, the fee radio app adds a social element. You'll have access to your friends' playlists that you can follow, and you can share music with friends. Offline listening with Spotify Premium will cost you $9.99 per month, but it ensures your musical experience isn't affected when you don't have a connection, and you can wirelessly sync your music to your mobile devices.
