Why use Fileora's online stopwatch
Many browser stopwatches count by adding a small step every few milliseconds. Browsers slow those steps down when a tab is in the background, so the timer quietly loses seconds. This stopwatch works differently: it remembers the moment you pressed Start and compares it with your device's clock, so the reading is correct whether you watched it the whole time or came back an hour later.
It is free, has no sign-up and shows no pop-ups over the timer. Nothing is sent to a server. Your times and laps stay in your own browser.
Ideas for using lap times
- Running and swimming: press Lap at each marker to see whether you are holding an even pace. A slowest lap near the end usually means you started too fast.
- Exam practice: press Lap after each question to find out which question types take you longest.
- Presentations and speeches: press Lap at the end of each section to check you are keeping to your time plan.
- Cooking and experiments: record each stage of a process without writing times down.
- Workouts: time sets and rests and paste the results into your training log.
Tips for accurate timing
Press the buttons at the moment the event happens rather than watching the digits. On a computer the keyboard is usually quicker and more consistent than a mouse, so keep a finger on Space and L. If you need to time several people, write down each person's total when they finish and use the lap table to compare them.

If you need to count down instead of up, the countdown timer sounds an alarm when time runs out. For focused study or work sessions with planned breaks, try the Pomodoro timer. To test how fast you type against the clock, use the typing test.
