App blockers for smartphones: when to use them and how

Executive overview

Smartphone overuse is a real problem, and the expert class often dismisses it — leaving people doubting their own experience. App blockers are a practical tool, not a moral panic. iOS imposes significant constraints that shape which approaches actually work.

Your instincts about your phone use are valid, and app blocking works faster than most people expect.

Why your concerns are legitimate

• The "expert" response to phone overuse typically takes one of three forms: belittling the word "addiction," reframing the apps as socially beneficial, or attributing concern to anti-tech sentiment
• These responses cause self-doubt and make people feel weak or disingenuous for wanting help
• The subjective experience of phone overuse — drifting from conversations, inability to read for sustained periods, treating loved activities as obstacles — is real and worth addressing
• Wanting help is not weakness; it is the correct response to a solvable problem

Three levels of intervention intensity

• Level 1 — Built-in tools: iOS Screen Time or Android equivalents; Freedom app. Provides usage reports, per-app daily limits, and time windows. Easy to circumvent — go to Settings and turn it off. Best for people who respond to nudges and minor friction
• Level 2 — Hard blocking with a trusted person: Screen Time's passcode feature (designed for parental controls) can lock your own settings if someone else sets the passcode without telling you. Set your restrictions first, then have a partner, friend, or family member set the passcode. You cannot override it without that person. Freedom can be layered on top using Screen Time to lock the VPN controls. On desktop or Android, Cold Turkey provides hard blocking natively — it integrates at the OS level and cannot be disabled by restarting or killing the process
• Level 3 — Full removal: Delete the apps or the accounts, or switch to a dumb phone. No settings to circumvent. Best for people who have no genuine need for the app and struggle with control

Why iOS is different from Android and desktop

• Apple banned third-party app-controlling apps from the App Store in 2018; Screen Time became the only sanctioned method
• On iOS, strong app blocking requires another person — there is no solo workaround
• On desktop or Android, tools like Cold Turkey work without involving anyone else

The end game: blockers as a training tool

• App blockers are not a permanent configuration
• The urge to check blocked apps fades within days to a few weeks of consistent blocking
• Once the craving is gone, removing the blocker often does not bring it back with the same intensity
• Moderation requires ongoing willpower; removal requires none — choose the level of intervention that matches the severity of the problem

Q&A highlights

• Transitioning from memory-based task tracking to a planner system: Task storage (what to do) and daily planning (when to do it) are separate problems. Use the lowest-friction storage system you will actually maintain — paper, Trello, Todoist — before worrying about scheduling tools like a time block planner
• Managing admin overload in academia: Four tactics — autopilot scheduling (fixed times for recurring work), office hours (replace async back-and-forth), communication protocols (defined processes for common requests), and deliberately doing a "passable" job on non-core admin rather than optimising for responsiveness
• Compulsive tweeting on desktop: Desktop-only means Cold Turkey is available without workarounds; alternatively, almost no career genuinely requires constant Twitter access — time-boxed use or full removal are both realistic
• Reading newsletters: Treat them like a curated magazine. File into a dedicated folder and read in batches once or twice a week, not reactively as they arrive
• Polyphasic sleep for deep work: Not viable. Human sleep architecture is biologically determined; attempts to hack it lead to fatigue. If time is the problem, do fewer things

Vibe coding: current state

• AI coding tools divide into two categories: autocomplete aids (Copilot, Cursor) that reduce boilerplate lookup, and vibe coding (generating code from scratch via prompts)
• Autocomplete is reliably useful and comparable in impact to the arrival of Stack Overflow
• Vibe coding has a variable success rate that depends on project complexity, the user's baseline coding knowledge, and the model's output on a given day
• Non-trivial projects built entirely through prompts frequently break in cascading ways that are difficult to debug without coding knowledge
• Claims that AI is eliminating software jobs conflate a post-pandemic tech contraction with AI capability; the reality is more nuanced
