The Problem

Your rest time
is being wasted.

In a world flooded with distraction, instant gratification and AI making us lazy, your cognitive power is quietly eroding.

Scrolling

Every rest period spent on social media fragments your focus and accelerates mental fatigue.

Cognitive Decline

Working memory, pattern recognition, problem-solving. Without practice, they degrade.

Wasted Potential

2 to 3 hours of unused time every week. Every session. Every year.

AI Dependency

Outsourcing thinking to AI quietly erodes your ability to reason and solve independently.

Tenace Score

A unique score combining your physical and cognitive performance. The only metric that rewards your brain as much as your body.

Leaderboards

Compare your Tenace Score with your circle or the global community. Not just on strength, on intelligence too.
