The iPad has its limits, but it's really good at a few basic functions. Here are 20 useful apps that play to the iPad's strengths.
This article has been superseded by a more recent update, published on March 14, 2012, on the eve of the launch of the third generation iPad.
I previously said that the Apple iPad is only good for two things (I later added a third), but it's really good at those things. With that in mind, I've compiled a list of the 20 most useful apps for taking advantage of the iPad's strengths.
Keep in mind that this list is skewed toward professionals and technophiles who are using the iPad on a daily basis, but I also realize that these folks tend to use tablets like the iPad for non-work stuff as well, like reading the news in the morning during breakfast or a little entertainment on the plane during a business flight.
The best way to view this list is the photo gallery of screenshots of the 20 apps. But, you can also view the full text of the list below, including links to download each of the apps from the iOS App Store.
This is a 21st century newsreader based on your social graph. It displays news stories based on what's being shared by your friends in Twitter or Facebook and auto-formats them in a newspaper-like column format. You can scan the headlines and first couple paragraphs and then click through to the site to the open the full story right in the built-in web browser in the app. (Tip: search for TechRepublic or Jason Hiner and you can set us up as one of your sections in Flipboard.)
The best way to read books on the iPad is the Amazon Kindle app, mostly because it has a large selection of titles available and it does the best job of syncing between multiple devices -- iPad, iPhone, Android phone, PC, Mac, and more. Of course, there are also strong alternatives such as Barnes & Noble's Nook app and Apple's iBooks app.
The best way to collect, manage, and read business documents on the iPad is with Dataviz Documents to Go, which not only allows you to sync local files from your computer but also connect to cloud services such as Google Docs, Dropbox, Box.net, SugarSync, and iDisk.
Tablets are great for people who spend most of their days in meetings. For that crowd and everyone else who needs a task list and project planner, the best app I've found is Things. It's a little expensive ($19.99 at the time I'm writing this), but I've tried cheaper solutions and none of them are as easy to figure out and as powerful to use as Things. It has a few limitations (syncing between multiple devices), but it does a great job of getting the process out of the way and helping you effectively track and organize your to-do items.
5. Analytics HD
One of the great ways to take advantage of the iPad as a viewer is to use it for quick glances at business dashboard metrics. This even translates to the simple task of checking traffic metrics and user info for your website. If you use Google Analytics, the Analytics HD app is a great way to view site data from the iPad. (Also see QlikView, SAP Business Objects Explorer, and Roambi.)
The iPad is a surprisingly good note taker. The keyboard is about 80% as good as a laptop keyboard but the convenience of a more portable device is valuable. Evernote is a great note taking companion for the iPad, since it can auto-sync your meeting notes back to your PC and smartphone. Just keep in mind that it's an online service and so be careful that you don't use it for any business-sensitive data. For that stuff, you can use locally-controlled files with Apple's built-in Notes app, for example.
Now that we've talked about the value of using the iPad for note taking, there are ways to do it that go beyond just typing things out. You can use an app like Penultimate to jot down handwritten notes and sketch out pictures and diagrams. There are several apps that can do this (such as Adobe Ideas, Ideate, and Idea Boards) but I think Penultimate is the most effective. If you get tired of using your finger as the writing device, you can get an iPad stylus like the Bamboo Stylus or the Griffin Stylus. In addition to using it for notes, I've even used Penultimate to sketch out an idea for a colleague in a meeting. It works great as a mini whiteboard in a coffee shop or a taxi cab.
Twitter's official iPad app is the best way to access Twitter and is an example of the kind of imaginative new UIs that good developers will attempt once they get grounded in touch-based tablets like the iPad. Check out the way the Twitter app exposes more or less info by sliding left and right. (Other useful Twitter apps include Osfoora and Twitterific.) The bottom line is that Twitter is an amazing real time news aggregator, as long as you follow the right people.
9. TED Talks
By far, the most inspiring app on the iPad is the TED Talks app. TED is a series of events featuring some of society's most fascinating and innovative ideas and most influential thinkers. You'll definitely disagree with some of them, because there's a large diversity of opinions. But, there are a lot of talks worth listening to and they're all free. Many of the talks are short and succinct, somewhere between 5-20 minutes.
Pulse is another iPad news aggregator like Flipboard, only instead of building its sections based on social feeds it uses RSS feeds. Like Flipboard, it presents the info in a visually-compelling format using images from the articles that it is linking to. You can use the RSS feeds for TechRepublic and/or Tech Sanity Check if you'd like to use Pulse to keep up with our latest posts.
Yet another great news aggregator for the iPad is SkyGrid, but its specialty is pulling together news on hot trends in real time. It's not nearly as visual as Flipboard or Pulse, but SkyGrid helps fill in the gaps by surfacing hot news and articles that might have been missed by your favorite RSS sources and your social network.
ProPublica, a non-profit publication of investigative reporters, is doing some of the most important work in journalism today -- the work that has increasingly been cut out of the profit-driven newsrooms. Plus, they have an excellent iPad app. The three column layout gives you the latest stories from ProPublica (most of which don't make the mainstream news), the middle column links to good investigative news pieces from the mainstream media (many of the stories are buried), and the third column has ProPublica's "Projects" or groups of stories where you can stay up to date on on-going issues. Keep in mind that ProPublica is non-profit and funded completely by donations.
Another one of the best iPad news apps from a media organization is the NPR app. It lets you quickly skim top stories, read related text articles, and quickly add radio/audio stories to a playlist that you can then listen to all at once.
A real diamond in the rough among iPad apps is The Guardian Eyewitness, which features amazing photojournalism from around the world from the popular UK news publication. The photos look fantastic on the iPad screen and provide a great way to scan through some of the most important current events on the planet.
15. Big Picture
Another great world news photo app is the Big Picture from Boston.com, a site that has had some of the web's best news photographs and slideshows for a long time. While The Guardian Eyewitness app lets you scan world events, the Big Picture app lets you dive into them as there are full sets of photos from each event. The two apps compliment each other well and are great for visual storytelling of important news stories.
16. Rosetta Stone
The popular language software Rosetta Stone has an excellent iPad app called TOTALe HD. Unlike the Rosetta Stone iPhone app, which simply serves as a review for your full lessons on a PC or a Mac, the iPad app has basically all of the same content from the PC/Mac and delivers it in a multitouch experience. It also syncs back to the Rosetta Stone servers (for Version 4 of the software) so you can pick up right where you left off when you get back to your computer. You have to have a full license of a Rosetta Stone language pack and an online account set up in order to use the iPad app. You can't just buy language modules directly for the iPad app.
17. iA Writer
If you want to use the iPad for note taking, journaling, or writing, then iA Writer offers a very simple solution for writing and managing your files. It is a completely bare bones word processor that can save your stuff directly to your Dropbox. Another similar program is WriteRoom ($4.99) and there's always Apple's own Pages ($9.99), but at $0.99 you can't beat the price and basic capabilities of iA Writer.
Unlike the iPhone, the iPad does not come with a built-in weather app. However, The Weather Channel has filled the void with an excellent app that takes advantage of the tablet interface. I've never been a big fan of The Weather Channel's desktop PC widgets, but they've done a great job with the iPad app.
Let's face it, most of us geeks love space. The iPad itself was, in part, inspired by science fiction such as Star Trek. NASA has a strong tradition of sharing its space exploration advances and research and they've continued that tradition in multi-touch style with an excellent iPad app that lets you explore photography from satellites, see NASA's launch schedules, research historical information about missions, and watch NASA TV live.
I've been a Scrabble fan for a long time but hadn't pulled out a board in a while when the game suddenly saw a revival in recent years in digital form, including several knock-offs such as Words with Friends. My favorite way to play digital Scrabble is the Pass'n Play mode on iPad. But the iPad also has an individual learning mode, a local network mode, Party Play (where you can use an iPhone or iPod Touch as a tile rack), and a mode where you can play against a Facebook friend. So, you can have a little fun and expand your vocabulary at the same time.
