Chronology

Chronology lets you run and view multiple timers simultaneously.
You can create up to 12 separate timers that can be started, paused, and reset individually or as a group.

Timers can count upwards indefinitely or if you specify a countdown duration, they can count downwards from that specified time.

Once a timer reaches that specified time, it continues counting down so that you know how much time has passed since the countdown finished. Each timer can play an alert sound at the end of a countdown.
