Frequently asked questions
What kinds of timers does ChronoBlock offer?
A visual countdown timer and a stopwatch. The countdown comes with presets from 1 to 60 minutes and a custom duration up to 180 minutes.
Are these timers free to use?
Yes. Every timer on this page is free, runs in your browser, and needs no account, no sign-in and no installation.
Which timer length should I choose?
Use 1 to 5 minutes for breaks and quick resets, 10 to 30 minutes for a focused work sprint, and 45 to 60 minutes for deep work that needs a longer uninterrupted stretch.
Do you have a Pomodoro timer?
Yes. The 25-minute timer is the classic Pomodoro length: run it for the work interval, then open the 5-minute timer for the break.
