Roblox on PC is great. No doubt. I've heard from friends that Roblox on Xbox is also fairly good. This is the mobile app however, and the mobile app is absolute trash. The controls are the worst I've ever seen for a mobile app and the lag is terrible. Playing it feels like I'm trying to drink in a car going 50mph down a country road. Pure pain and misery. The home page however is great and managing my group without my PC is handy. Just don't play games. Save yourself the pain...
