Questions people ask
How do I start the 25 minute timer?
Press Start (or the space bar). It is already set to 25 minutes. A chime plays when it reaches zero.
Can I pause it?
Yes — Pause freezes the remaining time, and Resume continues from there. Reset returns it to the full length.
Does it keep time in a background tab?
Yes. It measures against the system clock, so switching tabs does not slow it down. The remaining time also shows in the tab title.
