Why does one quick check become 20 minutes?

While building CogniFocus, I realized most people don t consciously decide to stop focusing.

It usually starts with I ll check one thing, and then suddenly 15 minutes disappear. The dangerous part is how automatic it feels. You don t intentionally quit the session; your brain just slowly drifts away from it.

That changed how I think about focus apps. A timer can track time, but it doesn t react when your attention starts slipping. So, I started building around interruption recovery and attention protection instead of only counting minutes.

Curious if others experience the same thing too or if it s just me?
