PORTA is a unique collection of Swiss-German sign language gestures that cater to the needs of individuals with intellectual and multiple (sensory) disabilities. This app seamlessly integrates with both spoken language and Swiss-German sign language (DSGS), opening the door to linguistic development for all users.

The PORTA app features a wide range of sign language gestures, each accompanied by a sign illustration, video demonstration, detailed description, and corresponding image. Users can easily search for specific signs, making it a valuable resource for communication and learning. Additionally, the app offers an interactive learning game, similar to a memory game, where users match signs to their corresponding concepts.

The app is available for free without any additional requirements. However, users can unlock additional functionalities by registering within the app using their email and password. These enhanced features include creating personalized catalogs, where users can curate their own collections of signs by combining PORTA gestures with their own custom signs. Users can also create their own sign gestures, allowing them to document personalized signs such as name signs or specific signs for a child. These custom signs can be accompanied by personal photos or videos.

Furthermore, the app enables users to generate worksheets in Word format from their sign catalogs. Users can select signs and have the worksheets sent directly to their registered email address.
