IPhone timer as a stopwatch?

I needed to time something, and noticed that the iPhone timer has no seconds!

Is there a way to change this so that is shows seconds?

My Android had seconds, I thought this was in every phone. Do I need a special app for it for iPhones?

There's definitely a stopwatch in the iPhone. Just go to clock, and the hit "stopwatch" near the bottom of the screen. The just hit start to begin timing something.

Just use this. It works great on iPhones:

It's a web app. You don't need to install anything on your iPhone.
