There's a Hifi music player called HiBy R3 out in the wild this week, and it's made for Tidal alone. This is a mobile music player made by the folks at HiBy Music. It has a touchscreen and connects to Wi-Fi to play music specifically and solely through Tidal. It's not made by Tidal, but it works with its own version of the Tidal app - and that's it. This is the specificity you've been waiting for.
