Description by eric cesar Written by the developer, not by AppBrain. Click to read.
It’s a scientifically validated cognitive upgrade — engineered to boost your IQ in just 7 hours total.
Built on Research.
Designed for Results. Forget brain-training fluff.
This is dual n-back — the only method proven to actually increase fluid intelligence, with results published in New York Times, The Wall Street Journal and other top journals.
But here’s the truth: It’s brutal. It’s exhausting. It works.
If you can complete 20 sessions, you may unlock:
• Sharper memory
• Faster learning
• Enhanced problem-solving
• Stronger focus under pressure
Track your progress.
See real gains — backed by data.
All within a beautifully designed, customizable experience.
This is not for everyone. But if you’re hungry to evolve, The Challenge awaits.
This app is only available in English.
