About
Quartenson Tools is a set of free browser-based tools for short focus and visual-attention practice. Try Schulte tables, visual search, visual memory, peripheral awareness, and reaction time exercises. Each tool supports quick, repeatable sessions with clear metrics and same-setup comparisons. For deeper Schulte practice, the Android companion adds session history, pace analysis, heatmaps, trends, goals, and achievements. Built for practice and self-comparison - not diagnosis.
