We could have duplicated the top ten business apps for iPhone here, as nearly all of the top ten iPhone apps have iPad versions – but we do recommend that you download these apps on to your iPad anyway. But instead we've opted for the ten business apps that make best use of the high-resolution screen.
1/ Todo for iPad
Todo for iPad is a work planner that will keep you on top of all your projects and plans and uses the large screen to give even more clarity to your task list. Todo also allows you to sync your work planner across any other Apple devices via iCloud, or to other devices using Todo Online, Dropbox, iCal and Outlook.
Hootsuite is the Swiss army knife of social networks. It allows you to view and participate in all of your social networks with just one interface.
Hootsuite allows you to see who's saying what on Twitter, LinkedIn, Facebook, and on other social networks. You can make posts to multiple networks, add pictures, check your popularity with its' built in analytics, and create short URLs.
Free (The free service is limited to 5 social profiles and is ad-supported, the full version gives you unlimited profiles and additional features and costs $5.99 per month)
The large screen on the iPad compared to the iPhone and the new high-res screen on the iPad 3 just invites you to draw on the device, and with Penultimate you can do just that.
Penultimate is the closest you can get to having a pen and paper on the iPad. With it you can take notes, keep sketches, or share your next breakthrough idea - in the office, on the go, or home on the sofa.
Penultimate can manage as many notebooks as you can create, each with an infinite number of pages. View your list in a notebook carousel - or sort and scroll in a fast grid view. When your notebooks get large, you can browse quickly through all pages, or insert, delete, duplicate, and reorganise pages within and between notebooks.
Numbers is a spread sheet app designed specifically for mobile devices.
Built from the ground up, it lets you make compelling spread sheets in minutes — with tables, charts, photos, and graphics — using just your fingers.
Choose from over 250 easy-to-use functions. Enter data and explore results with sliders, steppers, pop-ups, and intelligent keyboards. Numbers works with iCloud, so your spread sheets stay up to date across all your iOS devices — automatically. And the Retina display on the new iPad makes everything you do in Numbers even more brilliant.
Mind-mapping tool Popplet is another iPhone app that benefits from the iPad's larger screen. Popplet is a platform for your ideas. With Popplet you can capture your ideas, sort them visually, and collaborate with others in real-time.
Popplet Lite is free but you are limited to just one popplet. The full version of Popplet lets you create an unlimited number of local popplets, which are stored on your iPad. You can also use the full version to create online popplets, which can be shared with and edited by other Popplet users, both on the web at popplet.com and on via the iPad application.
Word Lens is an on-the-fly translation service. Point the iPads' camera at anything you need translating, like a menu, road sign, or a document, and magically the iPad translates the document into English.
You can also type directly into Word Lens and Word Lens will translate. There's no need to be connected as all the translation is done on the iPad.
Word Lens is currently limited to just French and Spanish.
PDF Reader Pro takes the standard PDF reader and adds so much more. It enables you to view large PDFs on your iPad, convert a variety of file formats directly into PDFs, and you can fill and sign PDF forms.
PDF Reader Pro also allows you to annotate PDFs with sticky notes, and sync any file, or folder, on your device through iCloud and share files on Dropbox, GoogleDocs, Sugarsync and more.
Need to create a quick diagram, process chart, page layout, website wireframe, or graphic design? With OmniGraffle, your iPad touch screen is your canvas, graph paper, whiteboard, or beer mat.
Using simple multi-touch gestures you can draw shapes, drag in objects, and style everything until it's just right. Smart guides help you organise your document in a flash, and when you're done, you can share your creations via PDF export, or open them in OmniGraffle for Mac.
