Not literally, and any app that says otherwise is overselling. On a self-managed iPhone the person who set the block can undo it. What varies is how much work that takes in the moment, and that difference is the whole game.

Nothing you set on your own iPhone is permanent, because you still hold the settings. A block you created is a block you can remove, and no third-party app can take that ability away from you. Anyone promising to block an app forever is describing something iOS does not offer on a self-managed device.
There are three real levels, and they are genuinely different. A Screen Time App Limit is the weakest: it ends with an Ignore Limit button and one tap clears it. A session-based block is stronger: the app stays blocked for a defined period and relocks itself, so overriding means more than dismissing a prompt. Strongest is a Screen Time content restriction with the passcode held by someone else, because undoing it requires a person who is not you.
That third level is the closest thing to a permanent block that exists on iPhone. It is not permanent either, but the reversal stops being a private decision you can make at 11pm, which is usually the decision that matters.
So “how do I block an app forever” is the wrong question. The useful one is how much work undoing it should take, and whether that work happens before the urge or during it. For the everyday version of that tradeoff, see strict iPhone app blockers.
No. iOS does not let a third-party blocker guarantee that every possible bypass route is impossible. A blocker can reduce common escape routes and make an override more deliberate, but it cannot honestly promise to defeat every settings change, deletion, reset, browser route, or second device.
That does not make every blocker equally easy to override day to day. The practical difference is whether the block starts predictably and whether an exception is a deliberate, limited action or a convenient button.
Fella is designed for that everyday decision. Start a focus session manually or use a scheduled routine. During each blocking session, selected apps stay blocked with one 5-minute emergency unlock, then relock automatically.
Settings and permission changes. A blocker that needs a system permission cannot enforce a block if that permission is changed or removed.
Removing or resetting the device. A third-party app cannot guarantee that it will survive deletion or a device reset.
Other routes to the same content. An app-only rule does not automatically cover browsers, computers, or other devices. Check the product’s actual scope before relying on it.
Not on its own, no. iOS gives no app the ability to prevent its own removal, so any blocker, Fella included, can be deleted from the Home Screen or App Library. Deleting Fella ends the blocking it was doing. We would rather say that plainly than imply otherwise.
Apple does provide a restriction that covers it, though. Go to Settings > Screen Time > Content & Privacy Restrictions > Content Restrictions and set Deleting Apps to Don’t Allow. That applies to every app on the device, so the blocker cannot be removed while it is on. Full steps are on preventing apps from being deleted.
The honest caveat is the passcode. Whoever knows the Screen Time passcode can switch that restriction back off, so on a self-managed iPhone this makes an app hard to delete rather than impossible. It becomes a real boundary when someone else holds the passcode, which is the same pattern as every other level above.
| Common bypass method | Can iOS realistically make it impossible? | What stronger approaches can do | Where Fella fits |
|---|---|---|---|
| Ignore or override a time limit | No, not for every self-managed setup. | Use a passcode held by someone else, or choose a blocker with a fixed, limited exception instead of an open-ended override. | Fella has one 5-minute emergency unlock per blocking session; selected apps relock when it ends. |
| Pause or disable a blocking session | No third-party app can guarantee that every route is closed. | Make exceptions specific, short, and automatic rather than repeatable or open-ended. | Fella’s planned exception is a single fixed emergency unlock, not a pause. |
| Change permissions or Screen Time settings | No. A third-party blocker depends on iOS permissions to operate. | Explain required permissions clearly; use a passcode or accountability arrangement when that is necessary. | Fella does not claim to prevent Settings or permission changes. |
| Delete the blocker | No | A passcode held by another person can add external accountability around device restrictions. | Fella does not claim to prevent deletion. |
| Use a passcode or accountability person | It can make an override much harder, but not make every possible route impossible. | Keep the passcode or approval decision with someone other than the person trying to override the rule. | Fella is not a passcode or accountability-partner system. |
| Restart or reset the device | No. A third-party app cannot guarantee it survives every reset or device-level change. | Test noncritical rules after an iOS update and use broader device management only if that scope is required. | Fella does not claim to prevent restarts or device resets. |
| Use a browser, another app, or another device | No, unless a separate product or setup explicitly covers that route. | Match the tool to the route you need covered; app-only blocking is not browser, computer, or multi-device control. | Fella is an iPhone app blocker for selected apps. Unselected apps remain available. |
Stronger friction removes the easiest everyday exits. It can keep a chosen app unavailable by default and make the exception specific, short, and automatic rather than another decision to make in the moment. To compare tools before setting this up, see our iPhone app-blocking options.
It does not make an iPhone owner powerless. If you need an external accountability arrangement, browser coverage, or controls beyond one iPhone, choose a setup built specifically for that need.
Fella does not claim to be unbypassable. It is a focused iPhone app blocker, not a device-management or accountability product.
Its boundary is simple. Start a focus session manually or let a scheduled routine start one. During each blocking session, selected apps stay blocked with one 5-minute emergency unlock followed by automatic relocking. See how an emergency-unlock app blocker handles that limited exception, and why a fixed unlock beats an open-ended pause.
For the broader category explanation, see the iPhone app blocker guide. For the question of everyday friction, see strict iPhone app blockers. If Apple’s broad controls are not matching the job, compare a more focused Screen Time alternative.

Not literally. On a self-managed iPhone the person who set a block can remove it, and no third-party app can take that ability away. The closest thing to permanent is a Screen Time content restriction with the passcode held by someone else, because undoing it then requires another person rather than a private decision.
There is no setting that blocks an app forever, but you can stack the strongest options: a Screen Time content restriction or App Limit, Block at End of Limit turned on, Deleting Apps set to Don't Allow, and the Screen Time passcode held by someone you trust. That combination is hard to undo in the moment, which is what people usually mean by permanent.
No app can prevent its own deletion on iOS, including Fella. What you can do is set Settings > Screen Time > Content & Privacy Restrictions > Content Restrictions > Deleting Apps to Don't Allow, which stops any app being deleted while it is enabled. Whoever knows the Screen Time passcode can switch it back off.
Blocking the app is only part of it. Check the other routes to the same content: the website in Safari, another device, and reinstalling from the App Store. A complete block usually means an app restriction plus Screen Time Web Content restrictions, and Deleting Apps and installing set to Don't Allow.
Yes. Fella is an app, so removing it ends the blocking it was doing. If that is a route you want closed, use Apple's Deleting Apps restriction alongside it rather than relying on the blocker to defend itself.
Usually, given enough control of the device. Many iPhone blockers depend on Apple's Screen Time frameworks and permissions. Settings changes, app deletion, account or passcode access, and device-level recovery may remain possible depending on how the iPhone is managed.
It can. If a blocker relies on Screen Time access, changing that access can affect whether it can enforce blocks. The exact settings and safeguards vary by iOS version and setup.
If app deletion is allowed, removing a blocker can remove its ability to enforce future blocks. Screen Time can restrict app deletion; that safeguard is stronger when its passcode is held by a parent or accountability partner rather than the device owner.
A restart is not a reliable way to judge whether a blocker can be bypassed. Check the product's current support guidance and test noncritical rules after an iOS update.
No. Third-party apps operate within iOS, so they cannot honestly promise to remove every settings, deletion, reset, browser, or second-device route.
Not in absolute software terms. The closest options are a Screen Time passcode held by someone else, an accountability-partner approval system, or a hardware-based blocker like an NFC tag or card that has to be physically present to unlock.
Fella uses Apple's Screen Time frameworks and does not claim to remove every device-level exit. It blocks selected apps during manual focus sessions or scheduled routines. Each blocking session includes one 5-minute emergency unlock, followed by automatic relocking.
Network status alone should not be treated as a reliable bypass test. Check the blocker's current support guidance and test any rule on a noncritical app.
Do not assume offloading will either preserve or defeat a specific block. App and iOS behavior can change; test a noncritical setup or consult the blocker's current support guidance.
