During Google I/O we heard about native Office document support, and we were pretty sure that was built on the QuickOffice platform.
It looks like after Google Docs receives the updates to natively edit Office files, Google will be properly retiring QuickOffice from the Play store. From the Google Apps Update blog:
With the integration of Quickoffice into the Google Docs, Sheets and Slides apps, the Quickoffice app will be unpublished from Google Play and the App Store in the coming weeks. Existing users with the app can continue to use it, but no features will be added and new users will not be able to install the app.
Short and sweet. Google acquired and retired in around two years. Fret not though as Drive and Docs will be getting much better soon…
