Very good, but there can me improvements.

Overall, Im happy with Tweetbot. Its fast and reliable. Its definitely worth the price. Its simply to use.

Hopefully in the future, theyll add a feature for scheduled tweets. I had to go back and use Tweetdeck to get my scheduled tweets done. Id also love to see an option of pop-up tweets rather than having to scroll the app for the latest timeline tweets. Tweetbot does a great job with pop-ups for mentions and DMs, so why not customizable pop-ups for your timeline/feed?
