System-level blocking
Nohub uses built-in iOS capabilities to block adult websites at the device level, not just inside one browser or one app.
Cross-browser protection
Where technically true, blocking applies across the browsers you use on iPhone — not only one.
Background protection
Once turned on, blocking keeps working in the background. The app itself is mostly where you check progress.
Progress, milestones, levels
A timer counts the time since you chose to stop. Milestones and levels mark recovery stages along the way.
Discreet by design
Calm interface, quiet language, and a small footprint. Nohub is built to feel like a private tool, not a public statement.
Private by design
No accounts, no tracking. Your progress stays on your device.

Is Nohub a free adult website blocker for iPhone?
Nohub is free to download from the US App Store and does not require a subscription or an account. The App Store lists it as Free with In-App Purchases.
How do I block porn sites on Safari on iPhone?
Install Nohub from the App Store and complete the short setup. Nohub uses system-level iOS blocking capabilities, so adult websites are kept out of reach in Safari and other browsers where technically supported — without configuring each browser separately.
Does the blocking work in browsers other than Safari?
Yes, where technically supported. Because Nohub blocks at the device level rather than inside one app, protection applies across the browsers you use on iPhone.
Does Nohub keep blocking when the app is closed?
Yes. Once you activate the shield, blocking keeps working in the background. You only open the app when you want to check your timer and current level.
Do I need an account or a subscription to a VPN service?
No accounts and no external VPN service. Blocking runs on your iPhone itself, and your progress stays on your device.
