Quickoffice just lost over an hour's worth of my writing

If you own a Nexus 5, you have this app. Do not use Quickoffice. It burned me once early on, but in hindsight, I think I lost work because I didn't fully understand the somewhat complicated method for how to save documents in the app. I gave it a second chance, and used it with success for a few weeks.

This morning, Quickoffice burned me again, and burned me hard. I lost over an hour's worth of work. An hour's worth of my concentration. An hour's worth of my writing. And an hour's worth of my editing.

I finished with this app forever, and I will be fully wary of any piece of software with Larry Page's stamp of approval.
