My all friends was using this amazing app. So I download this too because its is very lite and the call quality is very nice too. I download it from appstore.
The best thing is its totally free of cost and download very fast. The design is very simple and much easy to use. It sync all contacts automatically from phone and sim or email address as well too.
The most important videocall is very clear with it. With this you can share photo, videos too. Its very use full to chat with friends too. The voice call is very nice and the sound is very clearly hear with it. I use it alot to stay connected with friends and family. Its the nice invention.
