Here is a new application called “Whatsapp shadow beta”. Here is one new feature which is not in the old version. By using this new version you can Hide your Online Status while chatting with others. But, this feature is not needed so. But, sometimes you get bored by chatting and more. At that time you can use this feature.
For example in Facebook Chat you can hide your Online status while chatting with other. Likewise, by using this new beta version you can also hide your status while chatting. In other words you will be invisible to other while on your chat. And you will not be shown in your friends online contact list.
WhatShadow Messenger will disable your Wi-Fi or data connection, when you’re inside Whatsapp. Once this was done, you will not receive any messages and you will invisible. If you want to visible again then open the WhatsApp again, then your Wi-Fi and data connections are turned on automatically and now you can start chatting.
