Hey guys, I came across this real nice free app for the Apple TV (4K and 4th gen only I think). Great game and nice music, no ads or IAP.
You'll have to download it from the app store in the AppleTV. It is a fun little game
at 185 MB. More info: https://appsliced.co/app?n=beat-sports&l=list
Edit: you can also to buy it through the iPhone’s App Store as suggested below.
