Concept of this app is good that we can check our message even in laptop and pc but people are using this app to spy anothers phone.
Layout and design are not so much attractive it is normal. There are also lots of advertisement that will interupt in between so it reduces the performance of app.
Feature and function are good that we can access our whatapp account to our pc and laptop but people started spying others phone.so there is some chances where improvement is required that the illegal spying got banned.
This app is useful but security service is very bad in this app. So still there is very problems where improvement is required.
