Is Zenbrox free?
Yes — the focus timer, all brain games, and most articles are completely free with no account required. Zenbrox Pro ($3.99/mo) unlocks all articles and premium downloadable resources.
Do I need to create an account?
No. You can use the focus timer and play brain games without signing up. An account lets you track your streaks, save session history, and access Pro content.
What is the Pomodoro Technique?
The Pomodoro Technique breaks work into 25-minute focused sessions separated by 5-minute breaks. After four sessions, take a longer break. It reduces mental fatigue and makes large tasks feel manageable.
Do brain training games actually improve focus?
Targeted cognitive training can improve specific skills like working memory and reaction time. Our games are built around evidence-based tasks — dual n-back, the Stroop effect, pattern recognition — shown to strengthen attention and cognitive control.
What is deep work?
Deep work is focused, distraction-free effort that pushes your cognitive capabilities to their limit — coined by author Cal Newport. Zenbrox is designed to help you enter and sustain this state through structured sessions and cognitive training.
