Short Answer
If you arrived on this page expecting to download or open a mobile app, there is nothing to install here. The listings you are looking at are industrial computers — physical, fanless hardware appliances built by Thinvent. An "app" is software; an industrial PC is the rugged machine that runs that software, 24 hours a day, in factories, kiosks, control rooms and vehicles. So the honest answer to "what is this app?" is: it is not an app at all, it is the computer that hosts your apps.
App, Operating System and Appliance — Clearing Up the Confusion
Three things get mixed up constantly. An application is a program with a job to do — a SCADA dashboard, a billing client, a digital signage player, a machine-vision tool. An operating system is the platform underneath it: Windows 11 Pro, Windows 11 IoT, Linux or DOS. An appliance (or industrial PC) is the sealed, mountable box that holds the processor, memory and storage, and keeps the application running reliably in a hot, dusty or vibration-heavy environment.
Industrial PCs differ from a desktop in exactly the ways that matter for uptime. They are typically fanless, so no fan bearing can fail and no dust gets pulled through the chassis. They run on a wide DC input, often 12V, so they can be wired straight into a cabinet or vehicle supply rather than needing a mains socket. They offer legacy serial connectivity such as quad DB9 RS-232/RS-485 ports for PLCs, weighing scales, barcode readers and older instruments, and they are validated for continuous duty rather than a few hours of office work per day.
