Wylmi is a free Android application designed for social and communication purposes, enabling users to initiate one-way video calls effortlessly. The app allows users to create a virtual intercom system for their buildings or workplaces by generating a QR code that visitors can scan. This process reveals a directory of residents or colleagues, allowing them to select a name and start a video call. Importantly, while users can view the visitors through their front camera, the visitors do not have access to the user's camera, ensuring privacy during communication.

In addition to video calling, Wylmi offers an optional module for door control, allowing users to open building doors directly from the app. This added functionality enhances the app's utility, making it a convenient tool for managing visitor access in residential or office settings. Overall, Wylmi combines ease of use with practical features, making it a valuable communication solution.
