As strange as it may be, Twitter on the iPad has (or at least had) the same design as the iPhone. Same layout with the same amount of detail on 4,7-inch screens rather than 12,9-inch screens. This seems to be changing, Twitter is testing a new construction with three different columns to show more content on the big screen.
Larger screens are better used
Gradually and somehow, Twitter is working on a new design for the official iPad app. This new design is basically change the layout of all objects to show more detail
The menu bar is no longer low, but is displayed side by side. He timeline and the content is in the center and on the right side another column with content is added inclination or variable depending on the menu where we are. This new design works in a natural and vertical format. Design similar to the one we have on the web version.
A "small change" but an important one in Twitter's app development. It can take advantage of screen space and beam flexibility, proof of all that Twitterrific, Tweetbot or Twitter Tweetdeck itself allows. However, I am afraid that in this sense Twitter operates a standard design: offering a "bottom" design that is understandable and useful to most users. Most users require something tangible and simple, providing additional settings, lists and multiple columns are not their idea. However, change is welcome.
In the last months Twitter is using new features and improving its applications on Apple platforms. We have for example a new feature feature, an option to upload live photos or a macO app return in October.
Twitter for iPad can be downloaded for free from the App Store. There is no way to force the new design to appear If you don't have one yet. So, we have to wait for Twitter to use it for all users, when it does, because it's probably just a test.
