Track how long you actually study, with a lap for every subject you switch to.
Space = start/pause · R = reset
Most students reach for a countdown timer, but a stopwatch answers a different question: not "how much time is left" but "how long did I actually spend." That number is more useful when you are studying for an exam across several subjects and want to know where your hours went.
Start the stopwatch when you open your notes. When you switch from one subject to another, tap the lap button instead of resetting. The lap list keeps the last 20 splits, newest first, so at the end of a session you can read down the list and see exactly how long each subject got.
There is no account wall here — the stopwatch runs the moment the page loads. Elapsed time is saved to your browser's local storage continuously, so if the page reloads, your laptop sleeps, or you accidentally close the tab, your time is still there when you come back.
Space starts and pauses it, R resets it, and a fullscreen button removes the browser chrome if you want a clean, large display on a second monitor or a study room television.
If you'd rather work in fixed blocks, the 25 minute timer runs the classic Pomodoro rhythm, the study timer adds ambient sounds, streaks and a leaderboard, and the aesthetic pomodoro timer pairs a countdown with calming visuals. There's also an ADHD timer built around shorter, lower-pressure blocks.

Create an accountA countdown pressures you to stop at a fixed time even mid-thought. A stopwatch just tracks how long you actually studied, which is more honest if your sessions vary in length subject to subject.
Use a lap for each subject switch — start the stopwatch, hit lap when you move from Math to History, and the lap list shows how long each block ran.
Yes. The stopwatch uses your browser's clock in the background, so switching tabs to look something up does not pause or reset it.
No. Elapsed time is saved to local storage as you go, so a refresh or accidental tab close picks back up from where you left it.
The stopwatch itself is free with no account. Peazehub accounts add automatic session logging and streaks for $29.99 one-time, no subscription.
