Using the app is as simple as pressing the 'hide status' button while you're having a conversation. At that point, Hide WhatsApp Status will disconnect you from the Internet (whether you're using WiFi or 3G) so that to other WhatsApp users you appear as disconnected, even though you can still see what they've written.
Hide WhatsApp Status is a simple tool for a simple purpose that will really please WhatsApp users. The best part? It's both easy to use and direct.
