The Pomodoro Technique
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. Work for 25 minutes (one "pomodoro"), then take a 5-minute break. After four pomodoros, take a longer 15-30 minute break. This cycle prevents burnout, maintains focus, and creates urgency. Studies show it improves productivity by 25-40% for knowledge workers. Use the custom timer set to 25:00 for work sessions and 5:00 for breaks.
Timer for Exercise and Fitness
Interval training (HIIT) relies on precise timing. Common intervals include 30 seconds work / 30 seconds rest, 40/20, and Tabata (20 seconds work / 10 seconds rest for 8 rounds). The stopwatch mode with lap function helps track interval consistency. Boxing rounds are typically 3 minutes with 1-minute rest. Planks and wall sits use the timer directly.

Exam and Study Timers
Practising under timed conditions improves exam performance. Set the timer to match your exam duration and work through practice papers. The time pressure during practice reduces anxiety during the real exam — a technique called "stress inoculation." Most standardised tests allow 30-60 minutes per section.
