What makes Rocrail extra interesting is the ability to control everything through a web browser (Rocweb) or mobile app (AndRoc) in addition to the regular program. So, you can control it via PC, tablet or phone. It's all possible. However, a license key is required for the latter, which costs a small amount per year.
Rocrail is built as a Server-Client Program, meaning that you can install the server on a PC, Raspberry, Laptop, etc., and install the client on multiple PCs or laptops, making Rocrail accessible from multiple devices. The possibilities are almost endless
