BLOCK UNDERDOG FANTASY.
Untilt blocks Underdog Fantasy on your iPhone — the app and site stop loading while a wall is up. Like PrizePicks, Underdog operates as daily fantasy in most states, which means sportsbook and casino self-exclusion programs frequently don't touch it. The wall covers it anyway.
What Underdog's own tools do
Underdog offers deposit limits and self-exclusion within its own settings.
The same DFS boundary applies: state exclusion lists built for sportsbooks and casinos usually don't extend to pick'em. If your protection plan is the state list, Underdog is likely outside it.
Account tools close the account. Not the phone.
Pick'em is engineered to feel lighter than a sportsbook — picks, not parlays; entries, not bets. Your reflex doesn't care about the vocabulary, and neither does your bankroll.
Untilt blocks Underdog's domains by default, in the same wall as the books. One hold covers the whole spectrum, whatever each app calls itself.
| Screen Time | Delete the app | Underdog Fantasy account tools | Untilt wall | |
|---|---|---|---|---|
| Blocks the app | Limit only | Until reinstall | No | Yes, while up |
| Blocks the website | Partially | No | No | Yes, while up |
| You hold the override | Your passcode | Reinstall | Locked for the term | Not mid-wall |
| Covers other books too | Per-app setup | No | No | Every covered book at once |
| Requires an account | No | No | Yes | No |
Three ways to block Underdog Fantasy on iPhone
1 · DIY Screen Time. Free and built in: set an app limit or block the website under Settings → Screen Time. The honest part: you know your own passcode, "Ignore Limit" is one tap, and web workarounds are endless. It's a speed bump you own the keys to. Full walkthrough in why Screen Time alone isn't enough.
2 · Delete the app + restrict downloads. Deleting Underdog Fantasy helps for a night — until a two-minute reinstall. Pairing it with Screen Time's purchase restrictions is stronger, but the website still loads, and the restriction shares that same passcode problem.
3 · A timed, maintained wall (Untilt). Untilt uses the same Apple Screen Time technology — without handing you the keys. One hold walls off a maintained set of 50 wagering apps and 50 gambling sites on this iPhone — Underdog Fantasy's app and website together, alongside every other covered operator — until the end time you chose. Walls are timed: free 1-hour walls forever, longer with Pro, and mid-wall there is nothing to toggle off. No account, no card, and everything runs on the device.
60-second setup
Install Untilt, allow Screen Time when iOS asks (one permission, one time — blocking is applied on-device, and Untilt cannot read your activity), then press and hold for two seconds. The wall goes up and Underdog Fantasy stops loading until the end time on the readout. When it matters most — mid-tilt, before the game, the moment the deposit urge hits — the whole ritual is one hold.
Questions
Does blocking Underdog also block season-long fantasy drafts?
While a wall is up, Underdog's domains don't load — all of Underdog, drafts included. Walls are timed, so a free 1-hour wall through a risky window still leaves drafts reachable the rest of the day.
Does this block the website too, or just the app?
Both. A wall blocks the covered apps and the covered websites together — Underdog Fantasy's app and its domain are each in the maintained catalog, and Apple's Screen Time technology enforces both on this iPhone.
Does it work on cellular, or only Wi-Fi?
Both. The block is applied on the iPhone itself, so it holds on 5G, LTE, and any Wi-Fi network without router changes.
Can I take the wall down early?
Free walls run one hour and then come down on their own. Ending a long wall early is deliberately slow — a 24-hour wait, then a 15-second hold. Untilt never claims to be impossible to bypass; iOS gives the phone's owner final control. It claims to make the next bet slower than the urge.
