I haven’t tested it on a RasPi 4 but it could probably be made to work. RasPi 4’s pin-out is backwards compatible with the RasPi 3, and the software is all written in Python with Nginx as the web server, so it shouldn’t be platform-dependent. You probably can’t just download the RasPi 3 Bartendro disk image and install it on a Pi 4 though. You’d likely need to download the software from the GitHub page and set it up with Nginx manually. I just went through that process on a Pi 3. Still working on ironing out a couple of kinks.
