StopWatch 4 all

StopWatch 4 all is a powerful Chrome extension functioning as both a stopwatch and timer, ideal for various sporting activities. It supports multiple stopwatches and timers running simultaneously, limited only by system memory, enabling users to track different events with ease. Each timer can be individually renamed, deleted, or transformed between stopwatch and timer modes, with customizable lap lengths and displays in km/h or min/km.

The app also runs timers in the background, ensuring audio alerts function even when minimized. It features swim timer functionalities to calculate stroke rates, photo capture, configurable beep alerts before time runs out, and supports multiple internal and external ringtones with adjustable volume settings independent from device volume. User data is preserved across restarts. The Lite version limits total running time to 5 minutes. Available in German, Italian, and English.
