TEHY is a mobile application designed for members of Tehy, a Finnish trade union. The app is connected to the Tehy membership register, which allows users to update their membership information and access personalized content. One of the key features of the app is an electronic membership card, which eliminates the need for physical cards.

Other features of the app include the ability to contact a shop steward, browse national and local interests negotiated by the union, access TEHY news services and magazine, view the training calendar and enroll for training, and access important materials such as the TEHY Career Guide.

Although the app is tailored specifically for Tehy members, it is constantly being developed with new features and improvements. However, please note that a Tehy membership ID is required to use the app.
