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 · 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 Screen Time vs a DNS wall.
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 in every browser, and the restriction shares that same passcode problem.
3 · A device-level wall (Untilt). Untilt filters this iPhone's traffic on the device through Apple's Network Extension. While a wall is up, Underdog Fantasy and every other covered service stop loading — app and website, Safari and Chrome. Walls are timed: free 1-hour walls forever, longer with Pro, and mid-wall there is nothing to toggle off. No account; the filter and its receipts stay on your phone.
60-second setup
Install Untilt, approve the shield when iOS asks (a one-time local Network Extension — traffic is checked on the device, not routed through anyone's servers), then press and hold for two seconds. The wall seals; Underdog Fantasy stops loading. 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. The wall filters DNS on the device, so covered domains stop loading in the app, Safari, Chrome, and in-app browsers alike.
Does it work on cellular, or only Wi-Fi?
Both. The filter runs 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 end on their own. Pro walls of 24 hours or more require a deliberate written exit — friction on purpose. 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.
