Multi Stopwatch

Run as many stopwatches as you need, side by side. Start and stop them together, or let solo mode keep just one running.

Every clock you're keeping — in one side panel. Multi Stopwatch lives in Chrome's side panel and runs as many stopwatches as you need, each with its own color, name, and laps. Track parallel tasks, time your intervals, or split your day between projects. AS MANY AS YOU NEED • Add unlimited stopwatches; rename any of them with a click • Each gets its own color and a numbered badge • Start, pause, and reset individually — or "Start all", "Stop all", "Reset all" at once SOLO MODE Flip one switch and starting any stopwatch pauses all the others. It turns the panel into an effortless time tracker: one click (or one keystroke) moves the clock from "Emails" to "Client work" — no math, no forgotten timers. LAPS AND EXPORT Tap the flag on a running stopwatch to record a lap. Every lap shows its split and running total. When you're done, export everything — totals, laps, splits, down to the millisecond — as a CSV that opens straight in your spreadsheet. FAST WITH THE KEYBOARD Press 1–9 to start or pause the matching stopwatch. The numbered badge on each card shows its key. SERIOUSLY ACCURATE Elapsed time is computed from system-clock timestamps, not a ticking counter. It's accurate to the millisecond and never drifts — not while the side panel is closed, not even across a browser restart. The toolbar badge shows how many stopwatches are running at a glance. PRIVATE BY DESIGN No account. No tracking. No network requests. The extension asks for just two permissions — storage and the side panel — and everything stays on your device. More at visualtimer.com
