Sleet is a new iPad Twitter app by Inglorious Apps that allows you simultaneously use up to four Twitter accounts using a split-screen interface. You can view your timeline, mentions, direct messages, lists, favorites, search and customize your views according to your needs.
If you don't have multiple Twitter accounts, you can still use Sleet to view different sections of your Twitter account at once. For example, in the top-right corner you can show your mentions, in the corner below that, your direct messages, and the entire left column can be used for your main timeline. You can have any combination of one to four different accounts and timelines displayed on the screen at once.
Just like many other Twitter apps, Sleet displays in-line photos and let's you view conversation with a single tap. Tapping on a Tweet will give a popup of options include replying, retweeting, marking as favorite, and copying the Tweet. If you tap on a photo, it will open up nice in a big in a popup and external links give you the option of opening in Safari or a popup.
I really like the idea of Sleet, but I admit that it still needs a little work. The features and design is there, but the performance is not. Scrolling isn't smooth and it was a little confusing to add a second Twitter account since I was already logged into a Twitter account. I look forward to see what Inglorious Apps does with Sleet and updates that improve performance.
