Line

This hugely popular messenger boasts more than 470 million users worldwide! Like many other messengers, Line allows you to make voice and video calls, share video files, text messages and pictures. The application is logged in by your phone number, but immediately after registration offers to log in by another e-mail. This is logical, if you'll suddenly loose SIM-card, you can access to the application with a lot of friends by e-mail.

Of course, the connection is made via the Internet, so, enjoying of this app often costs hundreds of times less, than calls to the mobile. Especially it works for international calls and correspondence. In this case you would be bankrupt long time ago with SMS-messages and calls. However, if you use the mobile internet and pay for traffic, the communication can be quite costly.

Immediately after the registration, the application tries to climb in your contact list of the phone book. It's possible to ban it, but, on the contrary, you can quickly find your friends and acquaintances, who also share the Line, and start conversations.

Hundreds of funny and unusual smiles will help you to quickly and emotionally be in touch with friends, fun stickers will make communication unforgettably fun.
Besides the basic functions, Line has a peculiar system of microblogging, which is similar to twitter, where you can write your thoughts and news, and friends can read and like all of this.

This popular app is made as cross-platform (and perhaps this is one reason of its popularity). This means that the application can be installed to any mobile OS, whether it's Android, iOs, Windows Mobile, or any other. It allows you to communicate with your friends regardless of their preferences in mobile devices.

This is a great messenger, which has all the functions of the same Skype, but it looks much nicer. Developers have tried to extend the functionality of conventional messenger and they did it quite good!
