Timer!

Timer! is a feature-rich time-management extension that handles multiple countdowns, reminders, and timers in one place. Create sub-timers under major timers, run them in parallel, and save configurations for quick reuse. Now available for Apple Watch, so you can manage time across devices with ease.

It shines for workouts, cooking, and daily task planning. Use it as an interval timer for workouts (Tabata, boxing rounds, yoga), as a kitchen timer, or as a to-do list and task manager. Time is priceless—you can't own it, but you can use it.
