One app family
CQ is the YeahLah app.
CQAndroid, CQDesktopLinux, CQWindows, CQiOS, CQMac and CQLMobile are the versions for different devices. One YeahLah name works in all of them, so your calls, messages, mail and contacts follow you between phone and computer. Each version updates itself.
Other ways to install
Linux users can use the self-updating installer from a terminal. CQ Desktop then checks for new versions itself.
