Tweetie 2 is the second version of the popular Twitter client for iPhone/iPod Touch and is a complete rewrite of original. It's also one of the most controversial updates in Apple's App Store history. Since Apple has no paid upgrade option for its mobile software, developer Atebits instead offered Tweetie 2 as an all-new app, forcing owners of the previous version to pay out again.
It's worth the $2.99 price, though. It's noticeably faster than the previous iteration, and easier to use, too. It saves its state between tweeting sessions so that if you get a phone call or quit the app, it brings you right back to what you were looking at. It can also work offline, allowing you to queue up tweets to send even if you don't have a live Internet connection. Other improvements include full landscape support so that you can both browse and type in Tweets while holding your phone sideways, the ability to add multiple media attachments to a single tweet, and translation for foreign language tweets without exiting the app. It's also got a really neat location-based discovery mode that can help you find messages close to wherever you are. You can simply drag your finger around the map and it will refresh with new messages.
For all its reworked features, some have been lost. You cannot, for example, change the look and feel of the app beyond its stock theme. The app has also done away with its chat bubble style of presenting new tweets, except for in private conversations. Tweetie has still not adopted Apple's push notification service, something that would make it more useful when you're using another app. Tweetie 2 adds a handful of nice tweaks and improvements that make it worth the price of admission for users looking for a great, full-featured Twitter app.
