while GUI is important as that is what we interact trough, having a solid back end which is stable and responsive is even more important. When it comes to the GUI though, I heard that Tweetie might give them all run for their money.

Tweetie, a brand-new $3 iPhone Twitter client by Loren Brichter, is now available from the App Store. I’ve been using beta versions for a few weeks, and it is currently my favorite iPhone Twitter client by far. Tweetie shares a few conceptual similarities with Tweetsville, another very good new iPhone Twitter client — both take a very different approach than the king of the hill, Twitterrific.

The biggest difference is that both Tweetie and Tweetsville support loading additional tweets from further back in your timeline when you get to the end of the list. This makes it possible to “catch up” with older tweets in a way that just isn’t possible with Twitterrific. Tweetie also makes it possible to view individual users’ timelines within the app, using a left-to-right “drilling down” metaphor that allows you to go back to where you were. Tweetie wins out over Tweetsville by being faster, more stable (Tweetsville seems to more frequently run into low-memory situations when showing inline web views), and offering a more carefully thought out interface. The only thing I dislike about Tweetie is the SMS/iChat-style tweet list.
