For users who need secure messaging due to work or personal reasons, BBM
is a great choice. Now available on iOS and Andriod as well, it is more
platform friendly. They have also incorporated a lot of popular
features like voice, video chat and personal timeline (channel). Unlike
most chatting apps, BBM is less colourful and more business-like, a
desirable feature for some users. However, BBM is not the most
user-friendly application for the non-BlackBerry user. App use through,
seems a lot more robust than most of its chatting counterparts.
