My Turn is a simple app that shows a notification and plays a sound when it is time to take turns. This app runs in the background.
Do you need to share your iPhone or iPod touch with multiple people? Do you have kids that fight over the iPhone? Set a turn duration, then close the app. A message with a sound will let you know when it is time to take turns. The first turn gets a few more seconds so that you have time to close the app.
Requires iOS 4.
