I have a few different stopwatch apps for variety. Although my most-used one is the built-in Apple stopwatch that is part of the Apple Clock app, Best Stopwatch is my favorite out of my alternatives, as I like the slick neon color appearance and the easy differentiation between the stop and lap functions. If you are going to use any stopwatch other than the one Apple builds in, this is the one to get! I’m taking off only one star because I do agree with others that it could be a bit more readable - perhaps with a sharper and/or bigger font - but even so, I think it’s very good as is, especially as a free app.
