With the goal of giving users a familiar experience no matter what device they're on, the new Twitter has four universal buttons: Home, with your familiar feed; Connect, where you can see all your @replies and mentions; Discover, the place to check out trending topics and search hashtags; and Me, where you can dive deeper into your profile.
On top of that, the user interface has been given a makeover, with the pen in new Tweet button taking the form of a quill -- a clever nod to Larry, the bird in Twitter's logo.
If you don't have the new look yet, you can browse the redesigned iPhone app in the gallery below.
