How to set timer for 20 minutes intervals
Set timer for 20 minutes, choose a break length, and select how many cycles you want to complete. The default is 20 minutes of work followed by a 20-second break, repeated for 8 cycles.
The countdown derives remaining time from timestamps, so backgrounded tabs and paused intervals do not lose time through missed ticks. Use classic 25/5 Pomodoro-style values or adjust every field to fit your routine.
remaining time = phase duration − (current timestamp − phase start timestamp) This tool is a timer, not medical advice. Take breaks that suit your needs and follow guidance from a qualified professional for eye or vision concerns.
