    Three stopwatches for warmup, main, and cooldown

    This page opens the swim preset: three named timers ready for warmup, main set, and cooldown. Switch tabs between sets without resetting the whole board.

    Deck-side phones get wet and locked. A browser swim stopwatch on a tablet stays readable, private on device, and easy to share after practice. For single-lap track work, use the lap timer landing instead.

    1. 01

      Pick a set tab and start

      Use warmup / main / cooldown tabs, Start on the active set, and Lap for repeats. Add or rename timers from the hub if your practice plan differs.

    2. 02

      Record laps

      Press Lap or L to save a split. The last three laps stay on the stage; the table shows lap time, total, Δ vs previous, Δ vs best, and a bar versus your slowest lap. Best and worst rows are highlighted; tap the tempo chart to jump to a lap.

    3. 03

      Share, display, or go fullscreen

      Export CSV or share a read-only result link. Share a look with a hash URL for SEO-friendly bookmarks. Display (D) enlarges the stage and, once you have laps, shows status · time · Lap n · Best. Sleep (S) dims the page; F goes fullscreen — useful in gyms and classrooms.

    Why a swim-specific stopwatch page

    Multi-timer setup is the friction. This URL applies the swim preset so coaches and athletes land on three tabs immediately.

    What you get

    • Unlimited laps & live stats Record as many splits as you need, with best, worst, average, Δ vs best, a bar versus your slowest lap, optional hundredths or milliseconds, and an interactive tempo chart.
    • Background-tab accuracy Elapsed time uses wall-clock math, so it stays correct when the browser throttles hidden tabs.
    • Up to three timers Run parallel stopwatches for different athletes or drills, each with its own laps and session. Double-click a tab to rename it.
    • Copy, CSV & share links Export lap tables for spreadsheets, share a result snapshot URL, or share your look setup with a hash link others can open without hurting SEO.
    • Embeddable widget Drop a compact iframe stopwatch on your website with custom size, colors, and skin.
    • Looks, favorites & local sessions Instant Looks, digit styles, ambient sound, and saved favorites stay on this device — along with running sessions and recent history you can compare lap by lap.

    Frequently asked questions

    Shortcuts, laps, display, and sharing — quick answers.

    How many swim timers can I run?
    The swim preset starts with three. The stopwatch hub allows up to three named timers total.
    Can I rename warmup / main / cooldown?
    Yes. Edit timer names on the hub after the preset loads.
    Does it work poolside on a tablet?
    Yes in the mobile browser. Use fullscreen or display mode, and keep the screen awake with wake lock when available.
    Is this a pace clock?
    It is an elapsed multi-stopwatch for sets, not a wall pace clock. Use laps and notes for send-offs.
