All is good and what need more to comment.
But here as a review I can say that this is most simplest app for using to share information, messaging and it made simpler to live.
Amazing for those also who are less interact with these phones or are new in these .
I think this is the most simplest app still we are using for this work in the world. Now the news is also about in upcoming days it may be used as your wallet and this may bring change.because no one interested in storing extra app for wallet.
