Muzz (formerly muzmatch) enables users to track the status of each message:
Unread messages are denoted with two grey ticks. These ticks appear both on the individual message bubble as well as the Chat list.
Read messages are denoted with two pink ticks. These ticks appear both on the individual message bubble as well as the Chat list.
