A hard block is a wall. It's also, for most people, a temporary one — you delete the blocker, you flip the setting back, you reach for the second phone in the drawer. The wall doesn't fail because it's badly built. It fails because it removes a choice entirely, and a choice removed entirely is a choice you resent, and a choice you resent is one you eventually route around.
A hard block removes a choice; a gate makes you feel it
Most opens of the app you're trying to cut down on aren't decisions at all. They're a reflex — bored for four seconds, phone's already in your hand, thumb's already moving before the thought "should I" has finished forming. That's the behaviour a wall is fighting: not a considered choice, but the absence of one. Fighting an automatic habit with a total block is fighting it at the wrong layer — the habit never gets interrupted, it just gets rerouted to whatever isn't blocked yet.
A gate works differently. It doesn't remove the option, it inserts a beat before it. Answering a question takes just enough conscious attention that the automatic reach becomes, briefly, a decision you're aware of making. You can still choose to open the app after — that's the whole point, it's not a wall — but you choose it awake instead of on autopilot. Most people, given that half-second of awareness back, close the app instead. Not because they were stopped. Because they noticed.
Why a few minutes, and not twenty or twenty seconds
The gate has to sit inside a narrow band. Too short — a single tap to dismiss — and it's not friction, it's a formality; the reflex opens the app and moves past the gate in the same motion, no beat gets inserted at all. Too long — the push-ups problem from an earlier note — and the honest response isn't more awareness, it's disabling the blocker, because nobody keeps paying a toll that expensive at 11pm on a bad day.
A few minutes of three questions is short enough to survive a bad day and long enough that they can't be done on reflex. It's not a magic number so much as the rough size of "long enough to notice you're doing this, short enough to still be willing to do it tomorrow."
Where it stops working
This only works on behaviour you already want to change. A gate raises the cost of an automatic habit; it doesn't manufacture a reason to resist it. If you genuinely want to keep scrolling, you'll answer the questions and scroll — the toll gets paid, the awareness happens, and you open the app anyway, deliberately. That's not a failure of the mechanism. It's the mechanism doing exactly what it's built to do: putting the choice back in front of you, not making the choice for you.
It also isn't built for compulsive use that's past the point friction can reach — where the pull isn't habit but something closer to a dependency. A three-question quiz is a nudge for a reflex, not a substitute for professional help for a compulsion, and we're not going to pretend otherwise in the marketing to sell more downloads.
If what you're fighting is the reflexive kind — opening something out of boredom before you've decided to — that's the gap a three-question gate is actually built for. If it's something heavier than that, this app was never going to be the fix, and no amount of copy on this page should convince you it is.
