All versions of the iOS for the iPhone include Apple’s default clock app that features alarm settings, a timer, a world clock, and a stop watch. The clock app works well, but there are several pages of other free and inexpensive timer apps in the iTunes Store for both the iPhone and the iPad, the latter of which does not include a timer by default.
These timer and clock apps range from the very simple timer displays to more unique functions, such as interval timers, a few apps for timing meetings and presentations, and even a couple for clocking labor contractions.
I went through the pickings and selected ten representative apps, but you will find many more that might fit your needs. If you have a favorite timer app, please let us know about it in the comment section.
Interval Timer
The ad-based version of Interval Timer is a nifty fitness and workout app in which you can keep track of your work and rest periods during workouts.
The customizable sets for high/low intensity intervals is easy to configure, and it comes with a variety of alarm sounds (Bell, Boing, HipHop, Tiger, etc.) The app integrates with the iTunes library in your iPhone
