It was one of the headline apps when the iPad launched (and has been on the MacBook much longer), but well over a year since that iPad appearance, iWork has finally made it to the iPhone and iPod touch.Consisting of the individual Keynote, Pages and Numbers apps, each has been redesigned for iOS, allowing you to create and share presentations, formatted documents and spreadsheets on the go. 'Now you can use Keynote, Pages and Numbers on iPhone and iPod touch to create amazing presentations, documents and spreadsheets right in the palm of your hand', said Philip Schiller, Apple’s senior VP of worldwide product marketing. 'The incredible Retina display, revolutionary multi-touch interface and our powerful software make it easy to create, edit, organise and share all of your documents from iPhone 4 or iPod touch'.Keynote, Pages and Numbers import and export documents from iWork for Mac and Microsoft Office, print wirelessly using AirPrint and include Apple-designed themes and templates. All iWork apps now include improved document management with thumbnail images that let you find your files quickly, organise them and group them into folders using intuitive gestures. You can also share any presentation, document or spreadsheet without leaving the app.In terms of specifics, Keynote does your presentations, complete with animated charts and transitions. You can play your presentation in Full Screen view on the Retina display or connect to a projector or HDTV for a large audience. There's also a separate Keynote Remote app that allows your iPhone or iPod touch to control a Keynote presentation on any iOS device or Mac.Pages is the word processor, with Smart Zoom automatically zooming in to follow the cursor while you’re editing and zooming back out when you’re done. Numbers uses multi-touch gestures and the keyboard to help you create spreadsheets with over 250 functions, flexible tables and charts. Just like Pages, Numbers uses Smart Zoom to make working with text and cells on iPhone 4 or iPod touch easier.Want it? £5.99 secures it. Unless you already use the software elsewhere.
