Use UILocalNotifications.

3 notifications (ie. 13:00, 13:20 and 13:40) with repeatinterval:NSHourCalendarUnit..

Edit: Something like this:

UILocalNotification *localNotif = [[UILocalNotification alloc] init];

localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.soundName = UILocalNotificationDefaultSoundName;
    localNotif.repeatInterval = NSHourCalendarUnit; //Repeat every hour

localNotif.fireDate = [NSDate date]; //Now
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

localNotif.fireDate = [NSDate dateWithTimeIntervalSinceNow:1200]; //Now + 20 min
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

localNotif.fireDate = [NSDate dateWithTimeIntervalSinceNow:2400]; //Now + 40 min
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

[localNotif release];
