Alarm Clock Pro is a good alternative to filling your calendar with alarms and events. You can easily set alarms for specific times or intervals. These alarms can trigger scripts, sounds, alerts and actions for a variety of purposes.
You can also watch this video at YouTube (but with ads).
You can check out Alarm Clock Pro at http://www.koingosw.com/products/alarmclockpro.php.
It would be useful if you posted links to applications you discuss (http://www.koingosw.com/products/alarmclockpro.php, in this case). Maybe useful to you, also, in marketing MacMost? Or is it somewhere on the page and I'm just not seeing it?
I make sure the link is in the video since a lot of people watch at YouTube or through iTunes and won't see it here. Then I do try to remember to go back and add the link here in the post. Not sure how that helps me market, tho.
