How to Limit Roblox Time on iPhone (and Stop Purchases)

The free way to limit Roblox time on an iPhone is a Screen Time App Limit: choose Roblox, set a daily time such as one hour, and turn on "Block at End of Limit". To stop surprise Robux purchases, set In-app Purchases to Don't Allow in Screen Time's Content & Privacy Restrictions. Protect both with a Screen Time passcode, and use Roblox's own parental controls for chat and spending inside the game. Here's how each piece works.

Two separate problems: time and money

Roblox worries parents for two different reasons, and they need different fixes.

• Time. Games are built to be hard to put down, and "one more round" easily becomes an evening. An App Limit or Downtime handles this.
• Money. Robux can be bought inside the app. Screen Time's in-app purchase setting, Ask to Buy, and Roblox's own spending controls handle this.

It's also worth remembering that Roblox runs on consoles, computers and tablets. Anything you set on the iPhone only applies to the iPhone.

Method 1: Limit Roblox with Screen Time (free)

First, make sure your child can't turn Screen Time off. With Family Sharing, you manage their settings from your own iPhone (Settings → Screen Time → your child's name). Without it, set things up on the child's phone and turn on a Screen Time passcode that's different from the phone's unlock code. Our Family Sharing guide explains the setup.

Step 1: Set a daily time limit for Roblox

1. Open Settings → Screen Time.
2. Tap App Limits, then Add Limit.
3. Expand Games and select Roblox, or search for it.
4. Tap Next and choose a daily time, for example 1 hour.
5. Tap Customize Days if you want more time on weekends.
6. Keep Block at End of Limit on and tap Add.

When the time is used, Roblox locks for the rest of the day. Your child can request more time, which you can approve or decline. For help choosing sensible numbers, see how to set screen time limits on iPhone.

Step 2: Turn off in-app purchases

1. In Screen Time, open Content & Privacy Restrictions and switch it on.
2. Tap App Store Purchases (called iTunes & App Store Purchases in some versions).
3. Set In-app Purchases to Don't Allow.
4. While you're there, set Installing Apps and Deleting Apps to Don't Allow as well.

With in-app purchases off, Robux can't be bought through the App Store on that iPhone. If you use Family Sharing, you can also turn on Ask to Buy, so purchase requests come to you for approval instead of being blocked outright.

Turning off app installs matters too: it stops your child swapping Roblox for another game once the limit hits. The app blocking guide covers this in more detail.

Step 3: Keep Roblox out of bedtime

Late-night gaming is a common sticking point. Set Downtime for school nights so only Always Allowed apps work, and don't add Roblox to that list. Our bedtime and Downtime guide walks through it.

Step 4: Check the time afterwards

Screen Time shows how long each app is used each day and week. A quick look helps you see whether the limit is about right. See how to check your child's screen time on iPhone.

Roblox's own parental controls

Roblox has parental controls inside the account settings, separate from anything on the iPhone. These can include options around who your child can chat with, what kinds of experiences they can join, and spending. A parent can also link their own account or add a PIN so settings can't be changed without them.

Features and names change over time, so check Roblox's current help pages and go through the settings with your child. These controls follow the account across devices, which makes them a useful partner to Screen Time, since Screen Time only covers the iPhone.

Gaps to watch for

• Gift cards and the website. The iPhone's in-app purchase setting doesn't cover Robux bought on the web or with gift cards. Roblox's own spending controls are the place to handle that.
• Approving extra time by habit. Each "more time" request you approve extends play. Decide in advance when you'll say yes.
• A seen passcode. If your child has watched you type the Screen Time code, the limits are open to them.
• Other devices. A Roblox limit on the iPhone doesn't affect a tablet, console or computer.

Method 2: Manage Roblox with Skydo

Skydo is an iPhone parental-control app built on Apple's Screen Time technology (Family Controls). Blocked apps genuinely don't open, because iOS enforces it, not a VPN or profile.

Where Skydo helps with Roblox

• Homework Mode unlocks apps for a set time once homework is done, which suits families who treat Roblox as something earned.
• School Mode blocks apps during school hours on school days automatically, with the apps you allow still working.
• Bedtime and a daily time limit for overall phone use, both adjustable from your own phone.
• Block Roblox in a tap, or all games, if you decide it needs a complete break.
• Prevent installing and deleting apps, so another game can't replace a blocked one.
• Pause all apps for 30 minutes for dinner or a family outing.
• Parent PIN plus Face ID, plus a blocked-attempts count and weekly report.

Setting it up

1. Install Skydo on your child's iPhone and choose which apps to block. This list is set on the child's phone.
2. Install Skydo on your own iPhone and pair once with an 8-character code. No accounts.
3. Change bedtime, limits and school hours from your phone, and the changes reach your child's phone in seconds. More in control your child's iPhone from your phone.

Honest limits

Skydo must be installed and set up on your child's iPhone, running iOS 26.5 or later. It's free to download, but protection needs a Skydo Premium subscription (monthly or yearly); one subscription bought on your phone also unlocks your child's phone.

Skydo doesn't replace the purchase settings. Keep In-app Purchases: Don't Allow in Screen Time and use Roblox's own spending controls. And like any iPhone tool, it only covers the iPhone, not other devices your child plays on.

Finding a balance

Roblox is where many children play with friends, so a sensible limit usually works better than a sudden ban. Agree on the daily time together, explain the rules about Robux, and revisit them as your child gets older.
