How it works
Online Timer & Stopwatch in three steps
Pick a preset
Tap 1, 3, 5, 10, 15, or 25 minutes — or switch to stopwatch mode.
Start the timer
A large, readable display counts down or up so you can see it across the room.
Hear the alert
A sound plays when the countdown reaches zero. Pause and reset any time.
A timer that stays out of the way
Sometimes you just need a clean timer. This one is full-screen, large enough to read from across a room, and free of the ads and clutter that fill most online timers. Tap a preset, hit start, and get back to work.
Countdown or stopwatch
Switch between a countdown timer with one-tap presets (1, 3, 5, 10, 15, and 25 minutes) and a stopwatch that counts up. The 25-minute preset is handy for focus sessions; the short ones are great for breaks, presentations, drills, and timed tasks. When the countdown hits zero, a short sound lets you know.
Private and instant
It runs entirely in your browser — nothing to install, no account, no tracking of what you time. Recording a timed talk, interview, or study session? SozAI can transcribe it afterward into clean, searchable text with timestamps, so the timer keeps you on schedule and SozAI keeps the words.

Yes. Switch to stopwatch mode to count up instead of down, with start, pause, and reset.
What presets are available?
