Just a simple easy-to-read stopwatch with an intuitive split timer. Measures up to one-hundredth of a second (which is probably more accurate than your finger).
Continues keeping track of time when not in focus, but uses ZERO cpu time! Yay, finally someone figured out how to do it right!
Optionally vibrates and/or makes a sound on button clicks.
It's FREE! No ads, no nags, no internet connections, and no invasions into your privacy. It just works, dammit.
