The existence of this app suggests that "rino work" might refer to a specific job opportunity, recruitment process, or a platform for managing professional tasks at a company called Kitarino GmbH. It could also be a search for general information or user reviews of the app itself.
The + signs suggest the user originally attempted a Boolean search (common in older search engines or technical databases). This implies the searcher expected a very specific combination of terms. garea+perfectg+421+rino+work
