I have a couple of active Twitter accounts that I manage through Tweetdeck, the Twitter mobile app for iOS (on my phone), and the Twitter mobile app for Android (on a tablet).

I recently noticed that on iOS, the UI changed when I switched account:

Can you see the difference? When I use the app as @icareifulisten, the bottom ribbon has 5 buttons, with a “compose a tweet” button in the center. When I use the app as @tdnvl, though, the “compose a tweet” button is on the top right of the screen, right next to the search button.

My guess is that Twitter is A/B testing a new UI (isn’t everybody?) and they are rolling it out on random accounts, or for heavy users.

Have you noticed this too?
