Roblox is not one game. It is a platform full of games, events, friends, and always-available experiences. That makes it easy for a short iPhone or iPad session to become a long one.
Start with Settings > Screen Time > App Limits and add Roblox. Then use Sandflow to make each session visible in real time. When Roblox opens, Sandflow can start a timer; when Roblox closes, the timer stops.
Use a session rule before opening Roblox: one experience, one friend session, or one planned time block. If the timer reaches that limit, leave before choosing another experience. Turn off nonessential Roblox notifications so friend activity does not restart the loop all day.
