There are two primary ways of streaming Tidal from a phone/tablet to a network streamer, connected to your DAC.
The first way is to run the Tidal app on your mobile device and use an audio streaming protocol like AirPlay to send the data from your mobile to the streamer. You just need an AirPlay-compatible streamer or similar for that.
The second way is to sign-in to Tidal within the network streamer's app. So you will use the streamer's app to pick what music to play from Tidal.
The benefit to the first approach is greater product compatibility and using the Tidal app. The downside is you'll be limited to whatever codec the streaming protocol uses, which will possibly involve resampling and re-encoding. Just search for any product that lists AirPlay and has USB digital output.
The benefit to the second approach is the original audio data will be sent to the network streamer. The downside is you may not like the user interface of the streamer's app. For this you the streamer's product information must explicitly say Tidal is natively supported, and has USB digital output. You will want to research the streamer's app before purchasing, in case it turns out you really do not like using the app.
Roon is just an advanced software package for navigating and playing your music, from local files or streaming services like Tidal and Qobuz. It has some additional features but they're probably of little interest to you right now.
