Good on mobile.Worst on Laptop. I am advising everyone not to ues this app on PC.There are problames is loading the code.First the coad appears and we scan it but, then it says to scan again,then what!, the coad doesn't appeares again and whattsapp just eats our data.I have read many reviews, and all those who had given bad ratings for the use of this app on Laptop have the same issue.This is the problame of the app and it's the Creator's duty to fix it and have to fix it.
