Twitterrific, the original and yet most modern Twitter app on iOS, has updated to version 5.1 and with it comes a bevy of new features. You get muffling of #hashtags and domains, and you can tap on a muffled tweet to peek at it. Settings are now synced across your devices thanks to iCloud integration, and support has been added for img.ly, mobypicture, and twitpic. If you're on iOS 6, you also get Avenir as a font choice. There are even more improvements and enhancements as well.

If you already own Twitterrific 5, head on over to software update. If you haven't tried it yet, check out the version 5.1 highlight video below and then grab it from the App Store.
