9Respect for the no-install philosophy — we build with the same idea. One thing that kills browser timers on mobile is the screen locking mid-run: are you using the Wake Lock API to keep the display on, and does elapsed time stay correct when the tab gets backgrounded and throttled? If both hold, this genuinely replaces a native stopwatch app for gym use.
Yeah, absolutely — that’s exactly the kind of edge case we’ve been focusing on. We’re using the Wake Lock API to keep the screen awake during an active timer, and the elapsed time is calculated from timestamps rather than relying on interval ticks, so it stays accurate even when the tab gets throttled or briefly backgrounded. That’s a big part of making it reliable enough for gym use.
Lap splits plus keyboard shortcuts is the combination that makes this usable during an actual workout — I don't want to reach for a mouse between intervals.
Exactly — that’s the goal. Lap splits make it easy to track each interval, while keyboard shortcuts let you control the stopwatch without breaking your flow or reaching for the mouse. We’re aiming to make it feel fast and natural during an actual workout.
I tested the live stopwatch. Start, pause, reset, and the display work, but the product page and site copy promise lap splits plus the L shortcut while the current tool shows no Lap control, and pressing L did not create a visible lap. Since laps are a main feature in the listing, I would either restore that control or update the copy and direct people to the separate Lap Stopwatch.
This free online stopwatch is incredibly practical. It supports millisecond timing and keyboard shortcuts, works right in the browser with zero downloads needed.
