Tweetbot is a full-featured iPhone (and iPod touch) Twitter client with a lot of personality. Whether it’s the meticulously-crafted interface, sounds & animation, or features like multiple timelines & smart gestures, there’s a lot to love about Tweetbot.

Pros

1. Multiple Timelines. Quickly switch between your lists as your main timeline.
2. Smart Gestures. Use Twitter more efficiently with time-saving and configurable gestures.
3. Native Push Notifications.
4. Mute filters lets you block messages from users without unfollowing them.
5. Sync timeline position, direct message read statuses and mute filters between iPhone and iPad via iCloud.
6. Customizable Navigation. The last 2 tabs are customizable and unused tabs are easily accessible.
7. Support for multiple services like Pocket, Instapaper, Readability, CloudApp and Droplr.
8. Save drafts, add locations and POI’s, attach photos/videos/notes, manage your lists, and much more.

Cons

1. I wish for a unified account to view all the tweets for multiple accounts into one single timeline! Just like email!
2. I want a Alert filter so that I can set push notification for specific person, keywords or hashtags to push notified regardless if that tweets is for you or not – This is good for businesses to get notified for tweets that’s related to that company automatically without searching.
3. I hope for the ability to send multiple photographs or videos in a single tweet, there should be enough characters for two image url links if it exceed 140 characters then prevent the user from sending the tweet as usual 😀
4. Detail & conversation are basically the same, why not just use conversation and let user customize swipe to right as something else just like triple tap settings. I like to change “swipe to right” to retweet or quote and keep the “triple tap” as reply.
5. The “Add location” doesn’t detect my location accurately indoors, I hope I can search for a location & use that location within the tweet instead
6. I want to display more than 10 trending topics if possible maybe with a setting? I know it might not be possible but I pray & hope I can see more 😀
7. I want a method to translate my tweet text to a different language before sending the tweet 😀

There are so many features that the video will be 30 minutes long if I list them all into the video!

The iPhone version can work on the iPad with 2 times resolution but the iPad version cannot work on the iPhone so be very careful when buying!

Overall tweetbot is the BEST twitter client in the App Store and I had tried many.
