Think mission
A math alarm that wakes the decision-maker.
Arithmetic and digit recall add just enough conscious work between the alarm and silence.
Why math works as friction
The point is not intelligence or punishment. A small problem requires you to read, hold information, choose, and act—steps that an automatic swipe avoids.
Difficulty should be humane
An impossible mission trains you to disable the app. Ransom offers controlled difficulty and a finite number of required answers so the contract remains credible.
The universal fallback
Think needs no camera, tag, target object, or open space. That makes it the safe destination when a hardware mission cannot continue.
