Willpower is strongest before you're tempted, not during. Fella uses that: choose the apps and the hours once, and the block holds without needing another decision each time you reach for your phone.

The failure point is almost never planning. It's the moment the app is already open in your hand and a decision has to be made right then, tired, bored, or mid-scroll. An app blocker doesn't add willpower. It moves the one decision that matters to a calmer moment, hours or days before the temptation shows up, so there's nothing left to decide in the moment it usually fails.
Self-control isn't a fixed trait, it's a resource that runs down over a day. Research on decision fatigue and ego depletion consistently finds that resisting temptation earlier in the day makes the same resistance harder later on, which is exactly why the 11pm scroll is so much harder to resist than the 9am one.
An app open on the home screen is a decision waiting to happen, over and over. Every glance is a fresh chance to fail, and the odds get worse as the day wears on. Removing the option removes the repeated test.
Pick the apps that consistently win against your intentions. Not your whole phone, just the specific ones where "I'll just check quickly" reliably turns into something longer.
Start a session manually when you need it, or let a routine start one automatically for the hours you know are risky. Either way, the decision happens once, ahead of time, instead of every time the app is opened.
One 5-minute emergency unlock per session covers a genuine need without reopening the door to the thing you were trying to avoid in the first place.
The idea isn't new. A gym membership you've already paid for, an automatic transfer to savings before you see the money, a locked box for snacks; all of these work the same way, by making the disciplined choice happen once instead of repeatedly. An app blocker applies the same logic to your phone.
If you're specifically looking for the SelfControl app, see our page on SelfControl alternatives for iPhone, since the original Mac app has no iOS version. For the mechanics behind scheduling this automatically, see how Fella routines work.
Everything you need to stay focused, right from Home.
Not replace it, redirect where it's spent. Self-control used in advance, deciding once what to block and when, is more reliable than self-control used in the moment, deciding whether to open an app you're already looking at. Fella moves the decision to the first kind.
No. Willpower is a limited resource that depletes over a day, which is well documented in behavioral research. Using a tool to remove a repeated decision isn't a workaround for weak willpower, it's the same logic behind any commitment device, from gym memberships to automatic savings transfers.
Choose the apps that repeatedly beat your intentions, then start a session manually or let a routine start one automatically. Selected apps stay locked for the session, with one 5-minute emergency unlock rather than an easy override.
You can end a session by turning the routine off in Fella at any time, the same way you could put a phone in another room and go get it. Fella doesn't claim to make cheating impossible; it removes the low-friction version of it, the tap-to-ignore button that most built-in limits rely on.
Screen Time limits show a screen with an Ignore Limit button, which takes one tap and no real decision to dismiss. Fella starts an actual blocking session instead, with a single 5-minute emergency unlock rather than an open exit.
