Although there is no official support for Tumblr on BlackBerry 10, that hasn't stopped developers from tapping into their available API to offer some apps. Previously, we saw Trapeez arrive on BlackBerry 10 and now the same developer behind the recently released FlickrUp has gone ahead and released Bee for BlackBerry 10. Bee is a Qt app that has been rebuilt using native Cascades to offer the best possible experience on BlackBerry 10.
The features are, for the most part, as you would expect from Tumblr but there is a few things missing due to the limitations imposed by the blogging platform. For example, the 'Ask' options are not available nor is the messages inbox. With that out of the way though, Bee does support posting, reblogging, editing posts, liking and unliking items and of course, tag search. All the things you'd really need to use the service.
If you've been looking for a good Tumblr app, Bee might just be what you need in your life. It's available now in BlackBerry World for all BlackBerry 10 smartphones but if you're looking to get in on the action, it will set you back $1.99, which isn't all that bad. Not as good a free mind you but it is native and the chances of Tumblr releasing a native BlackBerry 10 app do seem slim.
