If you’re like most people, you probably use a stopwatch to time your activities. But if you’re like me, you might also use it to track time in different formats, such as minutes, seconds, or hours. There are a few things you need to know if you want to use a stopwatch on your iPhone. First, the watch’s timer runs in minutes and seconds. Second, the watch can track time in three different formats: minutes (1/minute), seconds (1/second), and hours (12/hour). Finally, if you want to track time in multiple formats at the same time, you can combine them into one call by pressing and holding two of the watch’s buttons at once. To start tracking time on your iPhone, open the Clock app and select “Time.” Then select one of the three formats that your stopwatch supports: minutes (1/minute), seconds (1/second), or hours (12/hour). To end tracking time on your iPhone, open the Clock app and select “End Time.”
