Many uses - multiple stopwatches
I’ve been using different apps for multiple stopwatches and most of them disappear from the store over time. Fortunately this one is here and it is the best implementation I’ve seen yet of multiple timers on an iPhone. My use is for everyday tasks and for timing the accuracy of vintage and modern mechanical watches and clocks I service. The app is super clean and easy to use and offers the option of very high fractions of a section resolution.
