Why deleting is not enough
The App Store is the loophole.
Underdog can keep the pick'em loop alive after someone decides to step away from traditional sportsbooks.
The urge finds the shortcut
The danger moment is not abstract. It is usually one app, one game, one deposit.
Stifle adds friction
Choose Underdog Fantasy and make that first path harder to open.
Direct answer
Can Stifle block Underdog?
Yes. Underdog Fantasy is included in Stifle's iPhone app blocking directory. Start with Underdog as your free first block if it is the app you delete, search for, and redownload most often.
Stifle is not affiliated with Underdog Fantasy. It is a separate iPhone guardrail that adds friction before the app opens.
Switch loophole
If Underdog Fantasy 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.
