Kogni
Dopamine app lock · for iPhone
Scroll less.
Know more.
Before a social app opens, Kogni asks one quick question: a word in a new language, a surprising fact, a bit of mental math. Then the app opens for a short visit.
How it works
A tiny pause that breaks the scroll loop
Pick the apps
Choose the apps that steal your time. Kogni uses Apple's Screen Time, so it never sees which ones they are.
Answer one question
Opening one shows a pause. Answer 1–3 quick questions — a word, a fact, a sum — and the app opens.
Visit, then the pause is back
When the short visit is over, the pause returns. No guilt and no hard lock-out: you can always get in.
