SymbioticReminder is a discreet reminder software.
Once you've done this, the second dialog box will appear and inform you that you'll receive a reminder in a set amount of time- be it 30 minutes or even 4000 if necessary. It really couldn't be easier.
Once the time has elapsed, your reminder message will display itself- making sure you never forget anything important again. The best part? The only application you need to run this software is iCal, which runs in the background and ensures you have an invisible, symbiotic reminder system at your fingertips.
