Free Browser Aim Trainer - No Download
Test your click reaction time and accuracy without installing anything. Twenty targets appear one at a time at random positions - click each as fast as you can. At the end you get your average reaction time, your best hit and your overall accuracy.

A fast reaction is wasted if your sensitivity makes flicks overshoot the target, and a well-tuned sensitivity does nothing if your reaction time is slow.
