The Problem

You can't catch a habit you can't see.

The moment you focus, your body relaxes in all the wrong ways. Jaw falls open. Head drifts forward. Breathing shifts. You feel it hours later as tension, fog, and that hollow exhausted feeling that no amount of coffee fixes. You already know nasal breathing is better. The problem is you can't monitor yourself while you're working. MewCop does it for you.

3h+

per day, unnoticed

The average desk worker mouth-breathes for over 3 hours per day during focused work — without ever noticing.

+18%

more oxygen via nose

Nasal breathing delivers up to 18% more oxygen to the bloodstream than mouth breathing. Your brain runs on that margin.

willpower can't fix this

Conscious habit change requires an external trigger. Willpower alone doesn't work for unconscious behaviors — the research is unambiguous.
