Android stopwatch for working out

I recently started learning Android development, and as a starting point I wrote a simple stopwatch application that I actually needed. Let's say you want to do 6 x 10 push-ups; the app will increase a counter every time you reset the timer (after the break), so you don't have to remember the number of sets you have already done.

Pretty useful if, like me, you seem to lose you lose your memory and confuse all these numbers after a few exercises, and are too lazy to write them down. I couldn't find app with the same feature, so I made the repo public and uploaded a .apk file that you can use to install the file. To be honest, it wouldn't surprise me if I couldn't find the right app because I didn't find the right keywords.
