A calendar approved by the dark side! With Dark Calendar, you’ll be able to summon a general meeting of the underworld in no time – just use the integrated SMS or email notifications to let everyone know about a scheduled event. Schedules can be easily printed for offline viewing and distribution among your fellow fallen angels, undeads, ghouls, witches, skeletons and ghosts who always try to go through every wall without sending an RSVP first. Personal schedules can be protected with a password for extra security. Make sure you don’t forget about a single important thing on Halloween eve.
