This is a timer with up to five intermediate alarms that vibrate but don't stop the timer; it looks like this when running:
The idea is there are 6 alarms -- one Main and 5 intermediate alarms. The main alarm is the total count down time; think of this as the regular time you'd set on a timer. At the end of this time period the phone gives off a small beep and vibrates twice. The intermediate alarms specify times when you want a notification, but don't want the timer to stop. For example, in a talk where the speaker is notified of having 15 minutes left, 10 minutes left, etc. The person timing wouldn't want to stare at the clock, but does want to promoptly notify the speaker of the remaining time. And of course wants to know when the entire time is up.

To use it, press
- Start / Start to start and stop the timer.
- Reset to reset the timer the the Main time.
- One of the bottom row buttons and then Set set one of the immediate alarms or main alarm. If you press Main first, you'll see the total count down time, so that at the end of this time, the phone will give off a small beep and vibrate twice; if you press 1 through 5 you'll set an intermediate alarm, so that when the time reaches this point, the phone will vibrate, but keep going.
- One of the bottom row buttons and then Unset you will remove the main timer (by first pressing Main) or one of the intermediate timers (by first pressing 1 through 5).
Here is quite possibly the most boring youtube video ever showing this thing 'in action'.
