Yet another important application has been added to Flathub, a service for hosting and distributing Flatpak applications: WPS Office, making it even easier to install and update on Linux.
WPS Office is an office suite for Windows, Linux, Android and iOS, that includes three components: WPS Writer, WPS Presentation and WPS Spreadsheet. The personal basic version is free to use (but not open source software), with a professional version being available for a subscription fee.
