Free online stopwatch with lap tracking, split times, data export, and full-screen mode. Start, stop, and reset instantly on any device — no signup.

Hi everyone! I am excited to share Stopwatch.is. The idea came from a simple frustration: most online stopwatches and timers are either cluttered with ads, slow, or missing features that people actually need. I wanted to build something that is fast, clean, mobile-friendly, and works instantly without requiring an app. During development, I focused on the little details that make a big difference—keyboard shortcuts, customizable timers, downloadable lap times (PDF, CSV & TXT), fullscreen mode, progress indicators, sound controls, and a responsive design that works great on every device. My goal wasn't just to make another stopwatch. It was to create the best free web-based stopwatch and timer that anyone can open and use in seconds. I'd love to hear your feedback, feature requests, or ideas for improvement. Thanks in advance for checking it out!

Lap export to CSV is a nice touch for something this simple, and the fullscreen mode actually keeps the start button accessible without any weird resizing on mobile.

@okanvgyo Thanks a lot! Really appreciate you noticing those details. 😊

I wanted Stopwatch.is to stay simple without sacrificing the little quality-of-life features that make it nicer to use. Glad the fullscreen experience and CSV export stood out! Take my love.
