Daniel Would is developing a Twitter app for the Nokia N900 named Witter that is steadily improving at each update. It’s still in early development, but Witter is already very functional. You can tweet, reply, retweet, and Twitpic in addition to viewing the timeline, mentions, trends, and direct messages.

The main thing I noticed in the current update is the addition auto-refresh. Daniel also included the option to change the refresh interval.

It may not look very pretty right now because there are no graphics within the app yet. However, keep in mind that it is built from scratch and users have the opportunity to try the it out and give feedback to the developer before it goes public.

Some things I would like to see in the update:

• Word-wrap tweets
• Friends’ avatars
• Easier way to reply (users need to long-press in current version 0.1.1-9 )
• Better Time Display Format (seconds, time zone designator, and year is unnecessary)

Witter is available for download in the Extras Testing repository. Send questions or feedback at Daniel’s blog or follow him on twitter @danielwould.
