Today Tapbots announced it will release a version of Tweetbot for Mac. The new Twitter client is now available as an alpha build at their website. Tweetbot for Mac will be a paid app once it is released and although the pre-release versions work on Lion, it will be released for Mountain Lion only.
From what I could see using this app today, it’s just like the app we’re used to on iOS. So iPhone and iPad users familiar with Tweetbot will feel like home. This alpha version is a very good start for Tapbots.
