"Just don't check your phone" is not a plan โ it's a hope. Your phone is designed by teams of people whose job is to make it hard to ignore. Expecting willpower to beat that, every single focus session, for months, is setting yourself up to lose eventually. The people who stay focused reliably aren't the ones with more willpower โ they're the ones who removed the decision from the equation entirely.
Why willpower loses to a notification
Willpower isn't a fixed trait โ it's a resource that depletes as you use it, which is exactly why the same person can resist checking Instagram at 9am and cave at 4pm without becoming a different person in between. If staying focused depends on winning that fight every single time a notification lands, you will eventually lose it, usually on the day you can least afford to. The fix isn't trying harder. It's making the losing option unavailable.
What actually removing the option looks like
On iPhone, this doesn't require a jailbreak or a separate device โ Apple's Screen Time framework (technically "Family Controls") lets an app you authorize temporarily restrict access to specific other apps you choose. That's the mechanism Divux uses for its block presets: you pick a group of apps once โ say, social media and messaging โ save it as a preset, and then attach that preset to a focus session. For the length of that session, those specific apps are locked. Nothing else on your phone is touched.
The scope matters as much as the mechanism. Locking your entire phone for the whole day feels like punishment and invites resentment โ you'll find a way around it or just stop using the feature. Locking three specific apps for the 50 minutes you're supposed to be writing feels like a tool you chose, not a restriction imposed on you. Same underlying mechanism, very different experience.
Set it up once, use it without thinking
The point of a preset is that you only make the hard decision โ which apps actually pull me away โ one time, while you're thinking clearly, instead of re-deciding it every time you sit down to focus. After that, starting a blocked session is a single tap: pick the preset, start the timer, and the apps are already gone for the duration. No new willpower required per session โ you already spent it once, setting the preset up.
Frequently asked questions
Does blocking apps during focus time actually work better than willpower?
Yes, because it removes the decision entirely instead of asking you to keep making the right one. Willpower is a limited, fluctuating resource that gets weaker the more decisions you make in a day. A blocked app removes the option, so there's no decision left to get wrong.
Won't blocking apps just feel restrictive?
It depends on scope and duration. Blocking only the specific apps that pull you away, only for the length of a single focus session, feels different from a blanket all-day lock โ it's a temporary tool for one task, not a permanent restriction on your phone.
How does app blocking work on iPhone without a jailbreak?
Apple's Screen Time (Family Controls) framework lets an app you authorize temporarily restrict access to other apps you choose, without needing a jailbreak or root access. Divux uses this to power its block presets โ saved groups of apps you can lock for the duration of a focus session.
