Once upon a time we chat was very much famous among users because concept of wechat is very nice but now they are not bringing anything new and voice chat is now most common feature of social networking platforms.
So it is good but outdated app.layout and designing needs major changes.features are very less and need to increase.it doesn’t work properly in slow net speed which is also the down side.however they have good sticker and great concept but if they will not improve it then they will be out of the competition.
