On the new 11 and 12.9-inch iPad Pros, the updated Tweetbot app will no longer display black bars at the top and bottom, as demonstrated in the screenshot below.
It's a much nicer viewing experience on Apple's newest tablets, with Tweetbot able to take advantage of the full edge-to-edge display.
Tweetbot for Mac was also recently updated, with Tapbots introducing an option to match the theme to the operating system setting on Mojave, turning on the darker theme automatically when Dark Mode is activated. Also new is GIF support in the compose window for the Mac version of the Tweetbot app.
Tweetbot for iOS can be downloaded from the App Store for $4.99. [Direct Link]
