Show HN: Online Timers
https://www.timerone.comMinimal online date calculators and timers: pomodoro, countdown, stopwatch, alarm clock.
Pomodoro is easily configurable with the ability to add additional timers and to set predefined break activities. I like to add a few leg and core exercises (variations of squat and plank) and some stretching. Helps me to remember to move away from the monitor and relax the brain.
