What to test in Accuracy
Accuracy challenges emphasize controlled pointer movement, precise target selection, and efficient visual search. They are designed to distinguish careful control from pure speed while still giving every run a clear score.
Aim Trainer
Acquire and click a sequence of targets as quickly as possible.
Precision Tracking
Keep your pointer inside a moving target for a high on-target percentage.
Visual Search
Find one odd symbol among many similar distractors.
How to compare your results
Screen size, pointer sensitivity, touch input, browser zoom, and device type can all change accuracy tasks. Keep your setup consistent when comparing personal bests.
All Ruth Performance Lab scores stay in local browser storage. These challenges are recreational personal-performance tools, not medical, psychological, educational, or employment assessments.
Compete against your own baseline
These challenges are designed for repeat play. Device, browser and input hardware can affect results, so the most useful comparison is your own score history on a consistent setup.
All scores are stored locally in your browser. They are recreational measures, not medical, psychological or diagnostic tests.
