Online Stopwatch

A free web-based stopwatch and timer tool serves millions of educators, students, and everyday users who need reliable timing without downloads or signups. The site was built around a single utility — countdowns, stopwatches, and classroom-specific timers — and grew organically by solving a simple, recurring need better than most alternatives. With 3.4 million monthly visits driven largely by search traffic, it monetizes through Google AdSense and a premium membership tier, generating an estimated $300,000 per month in revenue.
