NoBlueTick: No Last Read - The app hides read notifications for popular messengers such as WhatsApp, Facebook Messenger and Viber so that your contacts don't know when you've read their messages. The app also has chat sectors that display unread messages as small notes on your device's screen. This is very convenient for multitasking, as you can quickly read messages without interrupting the current task. Just tap the bubble to open a message on NoBlueTick.
