You delete Chalkboard Fantasy Sports
That helps for a minute, but the app is still easy to search and reinstall.
Fantasy and pick'em blocker for iPhone
How to block Chalkboard on iPhone.
Chalkboard combines sports conversation with player picks, so reopening can begin socially before it feels like a betting decision. Stifle helps you put friction in front of that exact app path.

Coverage status
Chalkboard Fantasy Sports can be your first free block.
Stifle starts narrow on purpose: block the exact app you keep reopening, not your whole phone. Full Protection is for the substitute app the urge tries next.

Why deleting is not enough
The App Store is the loophole.
Chalkboard can behave like a real-money pick'em trigger even when it does not feel like a classic sportsbook.
The urge finds the shortcut
The danger moment is not abstract. It is usually one app, one game, one deposit.
Stifle adds friction
Choose Chalkboard Fantasy Sports and make that first path harder to open.
Direct answer
Can Stifle block Chalkboard?
Yes. Chalkboard can be selected as a covered app in Stifle. Use it as the first free block if the social picks feed is where your loop starts, or cover it after PrizePicks, Underdog, or another picks app.
Stifle is not affiliated with Chalkboard Fantasy Sports. It is a separate iPhone guardrail that adds friction before the app opens, without trying to be a broad whole-phone blocker.
Why this page matters
Social sports talk can become the doorway back to picks.
The trigger may start with checking a community or following player discussion rather than intentionally opening a sportsbook. When the same app also offers real-money picks, that social entry point deserves its own guardrail.
Real-world pattern
Where Chalkboard usually fits in the loop.
Social-feed trigger
Opening Chalkboard to see sports discussion can shorten the path to making another entry.
Picks-app substitute
Chalkboard can take over after PrizePicks, Underdog, or Onyx is blocked.
Separate intent from access
You do not need to decide whether the app is a sportsbook; block it if it is the route that restarts the behavior you want to interrupt.
Switch loophole
If Chalkboard Fantasy Sports is blocked, what comes next?
This is the part deleting one app does not solve. If the urge moves to a nearby app, Full Protection is designed to cover the switch before it turns into another deposit.
