I recently had to start taking vitamins and i always forget to take them on time,
I would like an alert from the am,noon and pm to repeat everyday.
between reminder and ical which one is right for the job?
I don't know Reminder. iCal will certainly do the job. You can even make it play an alert sound. You might have to set up three events, one for each time of the day you need to be reminded.
I would say for something daily like this, reminders is best. Cluttering up your iCal with a daily event is not great, but reminders will let you create one entry that reminds your daily with a sound and message.
