With TwitterFon Pro, developer Kazuho Okui takes an already excellent Twitter client and makes it even better. This release is a stepped up version of the original TwitterFon, which is still free but now sports ads. Those willing to pay for an ad-free TwitterFon Pro will find the same clean interface with additional features that put this in the top tier of Twitter iPhone apps. If you are a more casual Twitter user, you may be happy sticking with the original TwitterFon.
Along with being ad-free, TwitterFon Pro's upgrades will appeal to those who take their Twitter life seriously. For example, TwitterFon Pro can manage up to four accounts.
Probably one of the biggest strengths it has over competitor Tweetie is rich text. Links jump off the screen and are easy to tap for quick access to links. For those who share links frequently, integration with bit.ly is a welcome addition that enables tracking of links through the URL shortening service. Instapaper integration is also available, which allows users to save web sites for later reading.
Twitterfon Pro runs neck and neck with Tweetie when it comes to its feature set. In fact TwitterFon Pro does more; yet some of the features are a bit counter intuitive or hard to dig out. For example, hanging up one of the four themes requires a rather convoluted series of steps (described here on the Twitterfon web site). To his credit, developer Kazuho Okui has pledged to clean it up in a future release. And the developer's Twitter feed is frequently updated with workarounds, bug fixes, and update information.
If you are a serious Twitterer then there is much to like with TwitterFon Pro. If the occasional tweeting is enough, then you probably will do fine without the upgrade. But it doesn't mean you won't get jealous when you see the shiny new edition of TwitterfonPro in the App Store.
