Ranked in these QuestionsQuestion Ranking
Pro Beautiful design
Pro Multiple accounts
Manage multiple accounts and get alerts for them
Pro Excellent search features
Type your search term, then select whether you want to search for tweets that contain that term or go straight to the user whose name is the same as your search term.
Pro Keyboard shortcuts
cmd+n, shift+cmd+enter -- pretty much every time I've thought "maybe this is the shortcut for that" I've been right. Super intuitive.
Pro App experience similar to web experience
If you're switching from using the web client, this app will be quickly understandable to you.
Pro Gets the latest API updates
Twitter is slightly infamous for making changes to the API. At least with the official client, you stay ahead of this.
Pro Officially sponsored
So you know it will always be supported and won't be randomly shut down.
Pro Clean & Functional UI design
Pro Multiple account support
Allows easy switching of accounts withing the app.
Pro Supports login verification
The official Twitter app is perhaps the only app to support two factor authentication or login verification, thus providing a necessary additional layer of security to your Twitter accounts
Pro Photo editing tools
The app has filters, automatic level balancing and ability to crop built in the app.
Pro Inline photos
Con Missing features that exist on iOS
Con "In case you missed" feature, showing tweets other users liked in your timeline
Features (can't be turned off) that disrupt chronological timeline and/or show sames tweets repeatedly.
Con Promoted tweets
Con Too many permissions
Asking a lot more permissions than most third party apps.
Con No widget
Recently took away the widget for whatever reason and that's not cool.
Con Pretty heavy
If you're on a "available-space" budget, the official twitter app is pretty bulky and you'll be better-off with a more lightweight alternative.
Con Lack of ability to view tweets in a proper timeline
Con Terrible cellular data management
If you have a limited data plan for your phone, don't be surprised if you find a whopping 800 MB consumption at the end of the month. The app really, really wants to download absolutely everything, even if you don't want to see or play anything.
