This is the bestest app till now I have used. Many competitors of this app came but none could survive in fornt of it. This is the best for chatting, sharing songs, videos, knowledge, fun and many more. Its calling function is not that good but even then all other function beat its this disadvantage. Its a complete edutainment pack. I always rely on this app for the formentioned functionings.
Its the best way to remain in connectivity and share ideas . Its privacy is always maintained.
