The Pomodoro preset is 4 rounds of 25 minutes focus and a 5 minute break, with a color change at each switch. Share it with a class or study group so everyone sees the same clock.
In the web app, open the presets and choose Pomodoro. The numbers above are the preset's defaults and can be edited.
Open the app, pick Pomodoro, tap Start. Edit the lengths for a 50/10 pattern or a shorter class block.
Study groups and classes can all follow one link, see a shared timer link with no signup. For teachers, see ClockKeepers vs ClassroomScreen.
Tap Broadcast to get a link, QR code and 5-letter code, then open the web app on any TV, tablet or laptop and enter the code. The clock follows your phone live, with no cast stick and nothing to install on the display. Free for 5 viewers, unlimited with ClockKeepers Pro ($7.99 once, no subscription).
The preset has four focus and break pairs. It does not add a longer fourth break; edit the segments if you want one.
