Where to start from! The best messaging app has a web version of it which quite a thought by the owners as now the whatsapp can be accessed without the phone. But probably the cons of this Web of version of whatsapp is that the phone needs a data connection the web version of it to run which is quite a let down considering the other messenger apps available in the store.
The working of the app is real quick, smooth and even the interface user-friendly is quite a plus point considering is a personal messenger site. Initially, there’s a barcode which should be scanned with the phone cam for the log in process and there’s no other option to sign-in or to create an account as it can only be created in the phone itself and then can be used on web by scanning as mentioned above, which I think should be considered as con which is diffucult to find in this app as its really popular and useful keeeping in mind its features.:)
