Stopwatch is an advanced time-tracking tool that gives you the possibility to start one or more stopwatches simultaneously, as well as to take snapshots with various checkpoints in time. It supports multiple threads and has intuitive features that can be tackled with ease by all user levels.

Installing this app is a fast job that requires minimal attention, since there are no special options or software requirements involved.

The interface of Stopwatch is user-friendly. The main window shows a stopwatch and the current time in the status bar. It's possible to display up to eight stopwatches that can be started, stopped, paused and resumed at the same time.

Snapshots are recorded to another window, separately for each stopwatch. This list can be selected and copied to paste contents in a text editor and save the document for safekeeping. Unfortunately, the utility doesn't implement options for saving or printing data.

The thread priority can be set to idle, lowest, lower, normal, higher, highest or time critical, depending on your preference. Moreover, you can change the refresh rate and transparency level of the control panel, hide the toolbar and status bar, as well as clear all snapshots to restart the job from scratch. Keyboard shortcuts are supported for all actions.

The software product had minimal impact on the machine's performance in our testing. It utilized little RAM and CPU to function normally, and it stayed stable throughout its runtime without affecting other active applications.

To sum it up, Stopwatch comes packed with practical options for starting multiple stopwatches and recording various checkpoints at the same time, featuring support for multiple threads. Too bad that it hasn't been updated by the developer for a significant amount of time.
