Twitterrific also gets updated with Apple Watch support.

Twitterrific’s glance gives you a fun, visual digest of the total number of favorites, retweets and new followers you’ve received over the past 24 hours. Think of it as a lightweight version of the Today View from the iOS app. It also displays the number of unread tweets currently waiting for you the next time you launch the iOS app. Note that Twitterrific’s push notifications (available as a one-time in-app purchase) are needed to take full advantage of the app’s features on Apple Watch.

I’ve used Twitterific several times on iOS. There’s no doubt that it’s a great apps but let me wait till Tapbots update their Twitter client, Tweetbot 3 to support the watch¹.
