Clumsy and slow
I am severely disappointed with this app. Instead providing a local editing interface, this app connects over data/wifi to a remote Linux server to edit, leaving you working in the full-sized Libre Office environment, so typing is laggy. Although integrated well with Dropbox and Google Drive, there is no direct editing and re-saving, leading to messy duplicates. IMO, not worth buying.
