My memory-limited machine won't run iCal.

Also, iCal is not suited to quickly setting a 5 minute or hour alarm (to stretch). When my granddaughter appears, I've used it to instantly have it beep every minute, continually, for 'hide and seek'. A Growl notification appears that my alarm has been going off, then changes to my alarm has gone off.

Though iCal's long-term alarms are designed well for careful planning, TinyAlarm is the program I had long sought for the unanticipated, simple alarm, as when baking from another room.

Appears appropriately as a tiny icon on the status line of the Desktop's menu bar. A click & set takes about 5 seconds. Its tiny interface takes up little chip memory.

The photo above shows TinyCal next to it (as the day of the month), and the two supplement iCal nicely. Does only one thing, and does it well.

Though I can't run iCal, I found TinyAlarm & TinyCal offered what I most needed from iCal. I use each several times a day.
