SmartDay Mac, an integrated calendar and organizer designed for wide-screen Macs, iMacs and MacBooks, is now available for public beta. Just remember: beta software is unfinished software, so use with care.

The app uses advanced logic to schedule tasks directly into the free time in one’s calendar, and offers control over task prioritization and time management. SmartDay integrates with the company’s cloud hub, mySmartDay.com, to sync with their iPad organizer, SmartPad. SmartDay Mac automatically syncs both events and reminders from iCal.

SmartDay Mac is available free for public beta and runs on any Mac with OS X 10.7 or above. It will retail for US$29.99 on the Mac App Store. You can sign up for the beta at http://eepurl.com/kVL81 .
