For people with ADD or ADHD, you could set the Meeting Timer for 60 minutes and start it on the hour. With this setting the Meeting Timer begins on the hour, then you receive a vibration on the 1/2 hour, at 5 minutes to the hour, and at the hour. Each of these vibrations are unique so you can tell what the time is without looking at a clock. The meeting timer then resets for the next hour automatically. This allows you to track time automatically for each hour. If you have medication you need to take at certain hours during the day, you can set an Alarm at about 1 to 5 minutes after the hour so you'll be able to differentiate these times from the Meeting Timer signals you receive every hour (Alarm vibrations last for 20 seconds). Any of the 12 Alarms will operate while the Meeting Timer (or Timer ) is in operation (however, the Alarms need to be set first before setting the meeting timer or the timer.
