BlackBerry shocked the messaging app industry by hitting 20 million combined iPhone and Android downloads in just a week after BBM went cross-platform. Now, new Android data from Mobidia provided exclusively to BGR shows that right after its launch, BBM pulled ahead of or matched major rivals in the key metric of weekly engagement. This is particularly impressive considering that consumers who have downloaded BBM have not had much time to build up dense network of contacts that would drive extensive engagement, nor does BBM offer the kind of range of games, stickers or other diversions that LINE and Kik feature. In the week of October 20th, BBM’s engagement was 40 minutes in the United States, moving well ahead of Tango’s 24-minute engagement level. It’s worth noting that Tango reached 130 million users last spring and it added gaming to its messaging platform already in 2012.
