A new strong competitor prepares to face the service of Whatsapp.

The free service will be available on Google's Android-owned smartphones, which works on most smartphones except Apple.

The service is similar to Watab in that it tells the sender when the recipient reads the message, and it also shows that the recipient of the message writes at the moment to respond to what he rose.

The new "chat" service from Google has involved more than 50 telecom companies around the world, according to the British Telegraph newspaper.

The service is still in its first experimental stages, as Google has not announced when this application is to be put on the market on a larger scale.

Some users have expressed fears that the messages exchanged in the new service will not be fully encrypted, which would mark security safety questions.
