MoTweets has a superb user interface, designed to run on every Windows Mobile screen resolution and it seems pretty much any finger size.
The standard Twitter timeline view is the first aspect if this client app that hits the mark - by reducing the size of the entries (but still including the avatars of the Tweeters) the timeline view cleverly expands the view of the 140 character tweet when each individual entry is selected. This offers a useful summary of what is being twittered.
Every menu option within moTweet enhances the user experience and seems to be there for a specific Twitter-centric purpose rather than the whim of the designer. By clicking on a Tweet with a URL in it for example, the menu offers you the opportunity to visit the URL. Entries without URLs don't display this option.
Retweets, direct/private messages, URL shortening, GPS location display, saved photos and live camera uploads are all available, while it is also possible to manage multiple Twitter accounts with moTweets.
What's more if you're opting for the free, advert displaying version, the ads don't distract. They're visible in between occasional twitters, but don't spoil the experience at all.
The options screen allows for the inclusion or removal of timeline buttons as well as managing the length of the timeline, the update delay and other general options. Oh and there's a choice of skins as well.
In short, this is THE Twitter app for Windows Mobile.
