ONE QUESTION AT A TIME
The guides.
Twenty sourced, cited guides: how blocking mechanisms actually work, what your phone's own Screen Time, Digital Wellbeing and Focus tools do and don't do, the real research behind widely repeated screen-time statistics, and the learning science the quiz itself leans on. Every claim here is checkable — sources are listed at the bottom of each page.
How blocking actually works
GUIDE
How do app blockers work?
Most app blockers don't block anything at the network or code level — they intercept the moment you try to open an app and put something between you and it. What that something is decides whether the block actually holds.
GUIDE
Apple Screen Time vs. app blocker
Screen Time isn't a weaker version of a third-party blocker — it's the same underlying system most iOS blockers are built on. The real question is what sits between you and the unlock, not which one is "stronger."
GUIDE
Make Screen Time harder to bypass
Screen Time set up carelessly is trivial to get around in under a minute. Screen Time set up deliberately closes most of the obvious exits — though even then, nothing on a self-managed device is fully unbypassable.
GUIDE
Why app blockers don't work
The typical app blocker doesn't fail because people lack willpower. It fails because the block is reversible by the exact same willpower it was installed to replace.
GUIDE
Free app blocker, no subscription needed
Several genuinely free blockers exist, mostly at the browser or desktop level. The trade-off for free is usually narrower coverage or weaker enforcement, not a fake product.
Your phone’s own tools
GUIDE
How to set app limits on iPhone
App Limits are built into every iPhone for free, under Screen Time. Setting them up takes about two minutes — making them hold up against your own future self takes one extra step most people skip.
GUIDE
How to set app limits on Android
Android's App Timers are free and built into Digital Wellbeing on most devices. They work well for the apps they cover — and not at all for the browser tab someone opens instead.
GUIDE
iOS Focus modes explained
A Focus mode isn't an app blocker. It's a notification and content filter — it decides what reaches you, not whether you can open an app that's already sitting on your home screen.
GUIDE
Android Digital Wellbeing explained
Digital Wellbeing is three separate tools bundled under one settings menu — a pause switch, a time budget, and a night-mode dimmer. Knowing which does what changes which one is worth setting up first.
GUIDE
Does grayscale mode reduce screen time?
Yes, measurably — but the honest version of that answer is narrower than most articles about it suggest. Grayscale changes how long you stay once you're in an app. It doesn't change how often you pick the phone up.
GUIDE
Minimalist home screen setup
A minimalist home screen isn't really about aesthetics. The changes that actually reduce reflexive phone use are the ones that add a half-second of friction between unlocking and opening the wrong app.
GUIDE
How to reduce notifications
The instinct to just turn everything off is understandable, but the actual research points somewhere more specific: batched, predictable notifications beat both constant interruption and total silence.
The actual research on screens
GUIDE
What is normal screen time?
There's no single correct number, but recent surveys converge on a real range: roughly four and a half to over six hours a day for adults, higher for younger age groups.
GUIDE
Screen time statistics worth trusting
A lot of the numbers that get repeated about phone use trace back to weak or unverifiable sources. Here's what actually comes from credible, checkable research.
GUIDE
Signs of phone addiction
There's no formal clinical diagnosis called "phone addiction." What researchers actually study, under a more precise name, has a real, validated set of signs worth knowing.
GUIDE
Is my attention span getting shorter?
The "shorter than a goldfish" claim is a myth with no real study behind it. The actual, credible research says something narrower and more specific — about task-switching, not raw attention capacity.
The learning science behind the quiz
GUIDE
How long to break a phone habit
"21 days to build a habit" isn't from a habit-formation study at all. The actual peer-reviewed research found a median of 66 days — with a range wide enough to make any single promised number misleading.
GUIDE
What is spaced repetition?
Spaced repetition is one of the more solidly evidenced ideas in learning science — not a trend, but a finding with roots in 1885 and consistent support in modern meta-analyses.
GUIDE
What is active recall?
Active recall — testing yourself instead of rereading — isn't just popular study advice. It's backed by some of the most consistently replicated findings in cognitive psychology.
GUIDE
Does micro-learning actually work?
Micro-learning is popular, but the evidence behind "shortness" specifically is much thinner than the evidence behind spacing, which micro-learning often gets credit for by association.
