Google has released an updated versions of its Docs, Sheets, and Slides apps which allow users to manage the files within their Google Drive. On the security front all three apps now support Touch ID unlocking in iOS. Accessibility has been enhanced with support for VoiceOver to create, edit, and share files across the apps. In addition screen magnification has been improved when using iOS zoom in feature.
None of that matters really if the apps don't help you with productivity, but these updates also bring a number of new features to working with Google's apps. Documents see addition of real-time spell-checking, which is a nice feature when typing on a tiny screen. Working within Sheets has gotten easier thanks to the ability to hide rows and columns within spreadsheets. Finally Slides has added grouping of shapes, allowing you to add, remove, and move images within a presentation from your iOS device.
You can find Docs here, Sheets here, and Slides here, all from the iTunes Store.
