So now we have got the alternative to Google Talk on iPhone, long back when Google Voice application on iPhone did not satisfy the terms and conditions of the applications (actually that application altered the UI of keypad of iPhone) on Apple App Store then Apple took down most of the applications of Google and they warned Google not to do that again.
Then slowly and slowly the applications from Google satisfying all the norms of App Store again started getting populated over the App Store. It started with GMail then Google 2-Step Authenticator and then few more applications came up.
This new application revealed at the I/O event help by Google named as Hangout is basically an add-on feature of the Google Plus Social Networking website wherein using this application you will be able to initiate chat with the users and then start any video or audio hangout with your friends on your Google Plus.
The only negative point of this application when compared with Facebook messenger is that you cannot see the users who are available online at that moment (which is available in the Facebook Messenger application). You can create a new message and then select any user which is available in your circle to send that message. This way when you enter the chat screen then you can initiate the video hangout also.
Now the free calling feature and video calling feature is available on Facebook messenger but only to the US users whereas Google Hangouts Application provides the same to all the users in all the countries where Google Plus social networking is accessible.
This application has also been launched for the Android users but you will just have to upgrade the Google Talk application on your Android phone and it will be converted to the Hangout Application, you can see the same on the Google Play Store.
The application is great and will be very useful for not only those users who are actually using Google Plus most of the times but for those users (like me) who prefer to use GTalk for the conversations rather than Facebook Messenger because it is embedded to your mailbox and thus it is easier for you to be in contact with the person who all are using GMail.
