The promise that Tweetbot would sync across my iPhone, iPad, and MacBook Pro using iCloud was a big deal for me and a primary reason I bought the apps. Unfortunately, this “syncronization” feature is wildly inconsistent. My estimate is that it works about 60-65% of the time. This appears to be a known issue, and sometimes disabling and re-enabling iCloud sync solves the problem. Sometimes, but not always. There are still a lot of great features here, but Tweetbot definitely doesn’t all that it promises.
