Stopwatch and Timer is an app that lets you track time, although it offers so much more than a simple stopwatch (like the one that comes on your Android). Its most outstanding feature is purely aesthetic: it lets you set any image on your device as the background of the stopwatch.
Aside from customizing the app's background image, Stopwatch and Timer also lets you change the look of the numbers (font, color, size, bold, italics, etc.).
Another of Stopwatch and Timer's interesting options lets you activate an alarm for when the stopwatch reaches a specific time. This alarm can be any sound on your device: alarm sounds themselves, songs, whatever.
Stopwatch and Timer is a great stopwatch app that offers some amazing customization options. Of course, it also comes with every feature a basic stopwatch should have.
