I’ve used Tweetbot from early versions and have thought it was the best Twitter app for iOS/Mac. It may still be, but I’m starting to look elsewhere. 1) Synching just doesn’t work consistently. If you are a multi-device heavy user, this is a big problem. Sometimes it works, sometimes it doesn’t. But never consistently enough to be reliable. 2) Support doesn’t seem to exist. Tweets unanswered after weeks (irony noted). Emails unanswered after weeks. Sad.
