Gentle Reminder lets you become engrossed in conversation; the timer reminds you in a gentle, visual way to leave for your train or next appointment.
Touch the clock face once to set any time from 15 to 75 minutes.
The clock face brightens gently at the time you chose. It makes no noise.
Gentle Reminder must be running in order for it to alert you with its own display; however, on iOS 4.0 and above, it will show an alert with no sound if the reminder time passes when it is not running. For all versions, it remembers the reminder time if you quit it and return.
