From the IconFactory blog:
Today we are pleased to announce that Twitterrific 5.11 with Apple Watch support is available in the App Store. Ever since we first saw Apple’s new wearable in action, we knew Twitterrific would be a great fit. There are a myriad of compelling features in this update so we wanted to take some time to share a few of them with you.
I find it fascinating to watch existing products evolve an Apple Watch app. Good read, especially if you are thinking about building your own WatchKit app.

Based on all the reviews, it would seem like any third party app is not really worth using because of the multisecond startup time and bad lag. Hopefully, native apps will solve for this.
