Supposedly tween is; but I’ve not used it. Honestly the fact that it seems to crash constantly and then when it’s not doing that timelines don’t consistently populate have made me so far not want to bother installing it on my new machine. It’s led to checking twitter only sometimes on my phone; which given that I haven’t missed it made me contemplate deleting it. But I think just not logging in or only paying attention to mentions and messages the better course of action. 🙂
