Mood Messenger is a nice application which can be used as a replacement to your regular Android texting app. It provides a friendly and well-designed interface and multiple interesting features that default messaging apps don't have. Thanks to its search function you can find specific texts in your conversations and you don't have to waste time reading multiple messages just to find the one that matters.
Users are allowed to customize the interface by picking from over 100 themes and different backgrounds. Each time you get tired by a layout style, you can change to a fresh one. The notification system makes sure you're informed when someone just replied or sent you a new message. It works by using vibration, sounds or LED. Another small, but rather handy feature is the typing indicator which simply lets you know when someone is typing.
In terms of security, Mood Messenger provides chat encryption as long as you're a premium user of this service. Moreover, you can keep certain conversations private and protected from being seen by other people that might access your phone, using passwords. In case one of your contacts bothers you, please use the blacklist function to block them from sending you messages.
