When I got my new Tilt 2 phone with Windows Mobile 6.5 on it one of the first things I had to do was get a Twitter app. A lot of folks recommended Twikini so I bought it and it didn't take me very long to realize it was lacking a few key features.
While researching I found out about TouchTwit. While Twikini and others have been around longer and seem to be more mature I have found the user interface and experience with TouchTwit to be superior. TouchTwit is only available through the Windows Marketplace for $4.99. Twikini is only $.99 however it is worth the extra cash to get the easier user experience.
I travel a lot and am often reading tweets in the car, on the plane, running between gates, and other times when I only have a single hand available. Being able to manipulate the entire program with my thumb is a huge plus. And yes, I know the dangers of walking, driving, and tweeting.
Other apps seem to still hold to the old Windows Mobile 6.1 design style where you have two menu buttons on soft keys and then need to use the stylus to access specific functions. Since I have had my Tilt 2 I have only used the stylus twice. Well designed apps won't have anything that even remotely requires you to use the stylus.
Despite all that there is still one key feature of TouchTwit that kills all other Twitter apps for Windows Mobile (at least those I have explored). TouchTwit displays the entire tweet, you don't have to click on it or tap on it to view the tweet. Twikini frustrated me because I constantly had to tap a tweet to read it all and then tab back to go back to the list of tweets. I can't figure out why - you would think it wouldn't be too much to display the entire 140 character message. TouchTwit displays the entire tweet in an easy to read fashion that has great touch feel navigational control. And did I mention it is able to show the entire tweet, all 140 characters.
So, if you want a fully developed Twitter app for Windows Mobile you will probably want to look somewhere else, at least for the time being while TouchTwit matures. However, if you are looking for a solid Twitter app that is easy to use on-the-go and can display the entire tweet in the list view then TouchTwit is a great place to start. You can try it out for 24 hours before you buy it.
Before you ask, I use TweetDeck on my PC. Until they come out with a Windows Mobile version I plan to stick with TouchTwit. If they do come out with a Windows Mobile version it will have to be as easy to navigate as TouchTwit while still bringing the TweetDeck experience to Windows Mobile.
You can follow TouchTwit on Twitter @touchtwitinfo. If you purchase it through the Marketplace on your phone then updates are easy to install.
