If you haven't heard of Quickoffice yet, it's a brilliant app that allows you to open and edit Microsoft Office files on your smartphone or tablet.
Google own Quickoffice and have just made the app free for everyone on both Android and iOS. Not only that, but if you sign into your Google account with Quickoffice, you'll be given an extra 10GB of Google Drive storage completely for free. However do note that this 10GB will only last for two years.
Quickoffice is an amazing app and is perfect for anyone who works with Microsoft Office documents regularly.
With Quickoffice now being free there is basically no need to use Microsoft's own Office Mobile app for iOS which requires a yearly subscription of £79.99.
