CHRONEX — Stopwatch & Timer

CHRONEX is a precision time management app with three powerful tools in one: stopwatch, countdown timer, and world clock. No ads, no sign-up, works 100% offline. STOPWATCH Start, stop, and reset with centisecond precision. Record unlimited laps — your best lap is highlighted in green and worst in red for instant performance analysis. Time displays use crisp monospace typography for perfect readability. COUNTDOWN TIMER Six quick-start presets: 1, 5, 10, 15, 30, and 60 minutes. Or set your own custom hours, minutes, and seconds. A beautiful circular countdown ring animates in real time, and an audible alarm sounds when your timer finishes. WORLD CLOCK Track time across 24 cities worldwide including New York, London, Tokyo, Lagos, Sydney, and more. Each city shows its current time, UTC offset, and a day/night indicator. Add, remove, and reorder cities to build your personal dashboard.
