The study timer and stopwatch

The Study timer is the heart of your study sessions. You choose how you work:

• Countdown: set a duration and work until the timer runs out; great for blocks of, say, 25 or 45 minutes.
• Stopwatch: start and stop whenever you want; Cognito simply counts along.

Link a subject to your session and your per-subject statistics stay accurate too. Every minute earns 1 XP and a finished session gives a 25 XP bonus; see How you earn XP.
