А101 is a free Android app developed by DOMYLAND that offers a range of features for homeowners. The app allows users to browse through all the available projects by the developer, view floor plans, prices, and descriptions of the infrastructure. The app also enables users to book an apartment, parking space, storage room, or commercial property.

One of the most convenient features of the app is the "resident's account," which allows homeowners to send requests, pay bills, participate in surveys, and receive important notifications. Additionally, residents can use the app to request services such as repairs, order products, and manage their accounts. The app also offers a platform for communication between neighbors, allowing them to post announcements and participate in meetings.
