The world never ends.
The session has to.

Roblox is one of the largest platforms a phone can hold. It reported roughly 132 million daily active users and 381.8 million monthly active users in 2026, logging around 35 billion hours of engagement across the platform in a year. It isn't one game. It's millions of user-built worlds, and there's always another one to try.

A meaningful share of that time comes from kids. Roblox's own age-checked reporting puts roughly 35% of daily users under 13, and among US children who play, 21% log more than 10 hours a week, over an hour and a half a day for that heavier-use group. Whoever's holding the phone, the platform is built to keep a session going far past "just one round."

Fella isn't trying to compete with the next world. It blocks Roblox by default, gives one 5-minute emergency unlock a day for a real check-in, then locks it again automatically, whether that phone belongs to you or to your kid.

Robux, loot boxes, and limited-time events aren't incidental to Roblox. They're load-bearing. Psychologists studying internet addiction have pointed to the variable reward schedule behind these systems as the same mechanism that makes gambling hard to walk away from: you don't know what you'll get, only that the next spin might be the good one.

The details are specific, not incidental. Reporting on in-game monetization describes near-miss visuals designed to make a loss feel like it was almost a win, countdown timers that manufacture urgency around limited-time items, and pricing structures built around chance rather than a fixed purchase. Roblox's own Creator Hub has recommended "chance-based merchandising," where players pay for a chance at an item rather than the item itself.

Researchers have documented real harm from this design. A University of Sydney study that interviewed 22 children aged 7 to 14 alongside their parents found that in-game spending mechanics in games like Roblox caused described harm to the children using them, with one line from the research summarizing it bluntly as feeling like "child gambling." Several ongoing lawsuits allege the platform's reward design was built to encourage compulsive play in children specifically.

None of that requires spending money to matter. The same variable-reward pull that drives purchases also drives just staying logged in "one more round" longer than planned, which is the part a blocker can actually address.

Roblox has a documented history of slipping past Apple's own limits. Multiple threads on Apple's community forums describe App Limits simply not applying to Roblox, and the most common root cause reported is Roblox quietly appearing in the Always Allowed list, a setting that overrides any limit set elsewhere.

The fixes people have found are workarounds, not guarantees. Removing Roblox from Always Allowed, turning on Block at End of Limit, and signing out of the Apple ID and back in have all been reported to help. Apple shipped a fix for part of the underlying bug in iOS 17.1, and some users still report inconsistent behavior after it, occasionally requiring a full device reset to fully resolve.

Even when App Limits do apply correctly, there's still the Ignore Limit button. One tap removes the restriction for the rest of the day, the same escape hatch that undermines Screen Time for nearly every app it's supposed to limit. Fella has no equivalent. There's no button that quietly cancels the block until tomorrow.

Unlike Netflix or Twitch, Roblox has no working browser fallback on iPhone. There's no official cloud-play or in-browser version for mobile Safari; trying to load a game there redirects back to the App Store listing instead of actually running anything.

That's genuinely good news for blocking it. With apps that do run in Safari, blocking the app alone leaves a real gap, since the same content is one browser tab away. Roblox doesn't have that gap. Block the app, and there's no quieter side door to slip through on the same device.

1. Add Roblox to your blocked apps. Pick it once during setup alongside any other apps that eat the day.

2. Let it stay locked by default. There's no Always Allowed list to accidentally leave it on, and no Ignore Limit button to fall back on when a friend's world just got a new update.

3. Use the emergency unlock for real needs. One 5-minute window a day covers a quick check-in on an event or a message from a friend, not a full building session.

4. Roblox locks again automatically. Nobody has to remember to close the door, no matter how many worlds are one tap away.

People who open Roblox for one round and lose the evening. If a limited-time event or a friend's new build reliably turns into hours, that's the exact pattern Fella is built to interrupt, on any account, at any age.

Parents managing a kid's device who want something that actually holds. If Screen Time's Always Allowed quirks or an easy Ignore Limit tap have already made that route feel unreliable, a block with no equivalent override removes the guesswork.

People who still want to play sometimes. A specific event, a friend's server, or a scheduled session doesn't have to disappear. The daily unlock covers real, intentional use without leaving the app open all day.
