BEST GAMBLING BLOCKERS FOR IPHONE.
Written by Untilt — one of the tools ranked — so the method is published and competitors win categories outright. Four tools worth your time: BetBlocker (best free, all-category), Gamban (best paid, multi-device), Screen Time (best already-installed layer), and Untilt (best for sportsbooks and prediction markets on iPhone). Details and losses below.
Methodology
Five criteria, weighted for the moment that matters: (1) does it block apps and websites; (2) can the person who set it up disarm it mid-urge; (3) does it cover the full sports-action spectrum — books, DFS pick'em, prediction markets; (4) cost to start; (5) privacy posture. Facts from each tool's public site as of July 2026; where a competitor wins a criterion, it says so.
The field, honestly
| Untilt | BetBlocker | Gamban | Screen Time | |
|---|---|---|---|---|

| Multi-device | iPhone only | Yes | Yes | Apple devices |
| Account required | No | No | Yes | No |
Pick by situation
All gambling, every device, zero budget: BetBlocker. The charity workhorse. Its iOS mechanism (VPN profile) is its weakest surface, but the price of free across five platforms is unarguable.
All gambling, every device, budget for polish: Gamban — independent testing pedigree and the sector's most established paid product. Our head-to-head.
A first layer tonight with zero installs: Screen Time. Free and already present; know its three holes before trusting it — they're structural.
US sports action on an iPhone — books, pick'em, event contracts: Untilt. Native on-device blocking, sealed timed walls built for game windows, the only default coverage of Kalshi and Polymarket, free hour walls forever. Our product — judge the claim against the criteria above.
Whichever you choose
Stack it with the account layer: self-exclusion at the books you use. And if betting has stopped feeling optional, the strongest tool on this page is the phone number at the bottom of it.
Questions
What's the best free gambling blocker for iPhone?
For all-category gambling blocking: BetBlocker — free, charity-run, multi-platform. For US sportsbooks, DFS, and prediction markets specifically: Untilt's free tier — unlimited sealed 1-hour walls with no account.
What's the best app to block sports betting specifically?
Untilt is the only tool on this list built specifically for sports betting — sportsbooks, pick'em apps, and prediction markets like Kalshi and Polymarket in one default blocklist, with timed walls designed for game windows. That's our product, so weigh the source; the methodology and the competitors' wins are published above.
Do any of these block Kalshi and Polymarket?
Untilt blocks both by default. The general gambling blockers were built before prediction markets became sports betting's side door and don't focus on them.
Are gambling blockers impossible to bypass?
No — and distrust any that claims it. iOS gives a phone's owner final control. The honest metric is how much slower the next bet becomes, and whether the tool holds during the minutes an urge actually lasts.
PUT THE WALL UP.
Hold once. Covered sportsbooks, DFS apps, and prediction markets stop loading on this iPhone. 1-hour walls are free forever; Pro holds longer.
