Stopwatch
You can use the player as a stopwatch to time yourself of your friends.
Begin- Tap this icon to begin the stopwatch. While the timer is running, this icon will change to stay “Pause” and tapping it will pause the timer.
Clear- Tap this icon to clear the current timer and all previous counts. While the timer is running, this icon will change to say “Count”, and tapping it will save the current time to the first available count. This is useful for timing several items at once, like a footrace.
