Twitter for iOS enables you to communicate 140-character messages, links, and photos to over 300 million active users.
A consistent experience across iPhone and iPad: Twitter now has one app for iPhone and iPad. iPad users can finally compose quoted tweets without going over the 140-character limit, can search trending topics, and can explore product and place pages. Twitter's adaptive UI serves up an optimum line length, font size, and view no matter which device you're using.
Easy tweeting: Press the composition button to go to a new screen where you can type a tweet, add a photo, and tag your location.
Great layout: Twitter is very easy to navigate on the small screen. The composition button sits up top, and the bottom rail includes Home, Notifications, Messages, and Me icons with descriptions underneath, so even first-time users will know what they're pressing. On your profile page, you can see how many people you're following and how many people are following you. You'll also see three buttons in the middle: Tweets (your tweets), Media (the photos and videos you've posted), and Favorites (the tweets you've favorited).
Profile customization: Unlike Facebook, Twitter enables you to customize your profile page with the header photo of your choice. To edit your profile, press the Edit Profile button on the top right. To edit your settings, view lists, get help, or sign out, tap the settings icon at top center.
Robust search: Searching Twitter is a pleasure. Click the magnifying button and type in an item, and you'll find Top Tweets or All Tweets about the person or topic. Toggle between the two to find the most relevant results. Under that you'll find pertinent photos and accounts.
Great shopping tool: Under Recent Searches, you'll find three categories that help you search @twittershopping: Shopping, Entertainment, and Places. Shopping lists tweets about popular products from popular accounts. Entertainment shows you movies, books, and apps to consume. Places lists tweets about destinations ranging from the faraway to local restaurants and boutiques.
140 characters or less: If you're wordy, then Twitter's 140-character limit won't work for you.
No linking or emoji buttons: Facebook enables you to click its Add a Link button or emoji button to search popular stories (or ones you've recently clicked) or a variety of emoji to add to your posts. It would be nice if Twitter offered the same functionality.
Twitter is a great communication and discovery tool, and the unified app for iPhone and iPad makes for a more consistent user experience.
