How does the Pomodoro technique work?

You study in short, fully focused blocks with breaks in between. The classic version is 25 minutes of focus and 5 minutes of rest, and after every fourth block a longer break of 15–30 minutes. A block is short enough to start without dread, and the breaks keep you fresh for the next one.

1. Pick one task - a chapter, a problem set, a stack of flashcards.
2. Start the timer and work only on that until the bell.
3. Take the break away from the screen: stand up, have a glass of water.
4. After four blocks, take the long break.

Which block length should I choose?

Timer	Focus / break	Good for
Quick start	15 / 3 min	getting going when you’re procrastinating or tired
Pomodoro	25 / 5 min	most studying: reading, flashcards, short problems
Long block	45 / 10 min	longer problems, writing, lab reports
Deep work	50 / 10 min	one big topic when you’re already in the flow
Custom	your choice	your school’s lesson rhythm or a plan from your study app

If you keep checking your phone halfway through a block, make the blocks shorter. If the bell keeps interrupting you mid-thought, make them longer.

Good to know

• The timer keeps exact time even when the tab is in the background, and the time left shows in the tab title.
• Your settings and today’s focus time stay in this browser only - nothing is sent anywhere.
• While a block runs, the screen won’t dim (in browsers that support it).
• The timer also runs in the chill room, so you can study to rain or fireplace sounds.
