About the study timer
Pick a study block, press start and put your phone out of reach. The finish time shows under the digits, and the countdown keeps running even if you refresh or close the tab by accident.
Shorter blocks (25 minutes) suit revision and flashcards; 50–90 minute blocks suit essays, problem sets and deep reading. Always follow a block with a short break away from the screen.
