ServiiGo lets you browse and stream all the media stored on your Serviio PRO server to your android device.
Note: ServiiGo requires the paid version of Serviio, Serviio PRO

Unlike DLNA based apps, ServiiGo uses a feature of the paid version of Serviio, Serviio PRO, that works over the internet as well as at home. This means you can now access all your media using 4G/5G mobile networks and WiFi hotspots away from home.
