I’ve tried several Twitter iPhone applications, Twitterific, Twitfire, Twittelator and most recently Tweetie. Here’s my take.

• Twitteriffic has a richly designed screen with a nice collection of settings that mirror the iPhone interface. It’s pretty fast, but unless you upgrade you get ads.
• Twitfire is essentially a quick way to get your Tweet out there. It’s very basic in design.
• Twittelator Pro allows you to choose from 5 designs, which is a nice touch. It’s quick and allows you to zoom in on any Twitterer.
• Tweetie is my new favorite. The initial screen is a little slow to load, but once it does things move along quickly. The navigation lines up closely with the actual Twitter you see on your browser making it easy to learn and memorable. Supports multiple Twitter accounts, which is a time saver. Also has a nice trends tracking feature and the ability to adjust font size. Most other features on Tweetie are found with other applications.

Tweetie is the one for now and only costs $2.99. I’m sure there will be another Twitter iPhone application very soon, and no doubt I’ll probably give it a try.
