A:
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];

I belive the notification can be: alert with buttons OR sound OR badge OR any combination of these.. I suggest using UILocalNotifications with only sound! It's also the only way i can think of to do this..

Well basically you cant.. You would have to launch a message and the user have to enter youre app. The only thing you can do is figure out when to play all the sounds and add notifications.. You probably dont need to count do you?You know when the sound plays. So figuring out the count and when to schedule what sound is simple math..

You could schedule a notification for every 2 hour. i.e: add a notification with fireDate 7 AM one with 9AM and so on up until 11 PM. And set localNotif.repeatInterval = NSDayCalendarUnit; for each notification..
