What 92,000 interventions show about opening apps on autopilot

Data through September 13, 2026

Between June and September 2026, 834 Cortex app users hit the pause 92,060 times. One in ten times they chose not to go in. Instagram caused 79% of all impulses; the peak hour was 9–10 pm; and the single strongest predictor of resisting was not the hour or the app but whether the person had just labelled the open as “autopilot” — that doubled the resist rate.

Source: Cortex app’s own anonymized analytics (Mixpanel), event “Impulse Recorded”, 90 days ending 2026-09-13. 834 users with at least one intervention, mostly Spanish-speaking (Argentina, Mexico, Spain, Colombia). Hours are device-local. “Resisted” means the user chose “do something else” after the pause; everything else counts as continuing, including skipping the shield. This is one app’s users, not a population sample.

Instagram is the habit; everything else is noise

Of 92,060 impulses, 72,967 were Instagram — 79%. TikTok was second at 15%. Facebook, X, YouTube and WhatsApp together were under 6%. Part of this is selection (people install a pause app for the app that hurts most, and in Spanish-speaking markets that is Instagram), but the gap is too large to be only that: Instagram is the default thumb destination.

Resist rates by app tell a second story. Facebook: 23% — people who monitor Facebook are, apparently, already half-decided to leave it. YouTube 13%, TikTok 11%, Instagram 9%, WhatsApp 8%, X 7%. X is the hardest to say no to, which matches its shape: a two-minute check, forty times a day, each one cheap enough to justify.

Naming “autopilot” doubles the chance of not going in

After the pause, Cortex app asks why you’re opening the app: work, leisure, or autopilot. 44% skip the question. Of those who answer, 53% say leisure, 30% autopilot, 17% work.

The resist rate by answer: autopilot 13.2%, leisure 6.3%, work 5.4%. Same pause, same app, same person — and the moment someone admits “I didn’t decide this”, they are twice as likely to close the shield. That is the whole thesis of the intention question in one number. It also says something uncomfortable: people who answer “leisure” resist less than people who skip (11.3%) — a deliberate label is also a permission slip.

The day peaks at 9 pm and willpower peaks at 7 am

Impulses by hour form a long plateau from noon to midnight with the top at 21:00–22:00 (about 6,200 each). The quiet hours are 3–5 am (under 750 each). So far, unsurprising.

The resist rate is the interesting curve. It is highest in the morning — 13.6% at 7 am, 12.1% at 8 am, 11.6% at noon — and slides all evening: 8.4% at 21:00, 8.0% at 22:00, 7.9% at 23:00, 7.5% at 1 am, 5.5% at 3 am. The hour with the most impulses is also an hour where the pause works 40% worse than it did at breakfast. If you can only protect one window, protect 9 pm to midnight.

Weekends are worse than Mondays

Impulse volume barely changes across the week (12,400–13,600 a day-of-week), but the resist rate does: Monday 11.5%, Tuesday 11.3%, Thursday 10.8%, Wednesday 10.3%, Sunday 8.4%, Friday 8.0%, Saturday 7.1%. The structure of a workday is doing some of the resisting for people; take it away and the pause has to do it alone.

What we take from this

One in ten is the honest number. A five-second pause does not stop most opens, and nobody should claim it does; what it does is make one in ten of them a decision, and — the intention data suggests — it works best on exactly the opens that were never decided in the first place. That is the case for a pause over a block: the block would have stopped the other nine too, and been removed within a month.

We will re-run this quarterly with the same definitions. If the numbers move, the page moves.
