In a post on the official Office blog, Microsoft has announced a major new version of OneNote for iPhone, iPad, and iPod touch.
First off, the update adds a much more rich editing experience. Now, files and formatting look the same across all devices. This includes things such as text, graphs, tables, borders, and more. If you draw on a note with a Windows tablet, the markings are then visible on your other devices, as well. All devices now support the ability to sync notebooks with Office 365 and SharePoint, as well as the ability to share files with other Office users. OneNote also now lets multiple people edit a note at the same time, much like Google Drive.
On the iPad, the OneNote app now features the Office Ribbon UI that we’ve come to know from Office apps for other devices. You can customize the font, color, size, style, and plenty more of text now, as well as insert and edit graphs and tables. On the iPhone, the app is finally optimized for the iPhone 5′s display, after only 8 months of waiting.
Finally, OneNote is now totally free. It use to be that you could only create 500 notes with the app before having to pay, but now that number is unlimited.
