Double Check Killer

When you receive a WhatsApp message ShutApp will raise a popup that will allow you to read the text but the sender will NOT see the double check nor your last seen will be updated.

*** Important: you'll be able to read ALL the message text not just a part (as in the notification) and you're NOT limited to 7 messages as WhatsApp notification is.

Two types of popup exist: normal and overlay (see images).

The first one is a normal - scrollable - popup.

The second option creates an overlay panel thay DOES NOT INTERRUPT your current activity. Even you can read incoming WhatsApp messages while chatting in another WhatsApp conversation.
In both cases you can chose the order of the messages.

Also in both cases, clicking the X icon will discard the conversations and the / icon will postpone message (if you want to read them later).

Another option allows you to read the messages when the phone is locked.
There exists an option to disable popup for specific contacts or groups.

You've *250* free popups then you should donate something to continue using this app.
