While I think it's safe to say Blaq at this point pretty much owns the third-party Twitter app audience on BlackBerry 10, that doesn't appear to be a concern for Nemory Studios who is currently working on Twittly. Right now, it's in development and there's no beta as of yet but NemOry has posted up a preview video and some screenshots of the development thus far for everyone to take a look at and it looks pretty sweet. Although things could change, the plan is to release the app for free with an in app purchase to unlock pro features. Have a look and swing by the CrackBerry Forums to let NemOry know what you think.
