Working on pushing out more the iOS goodies to the many iPhone/iPad users. Sunrise Calendar is a terrific app that you can use to pull together a real-time Google Calendar with Facebook events and a myriad of other notifications. I’m told the integration is very good and lets you respond to items and reschedule events easily and quickly. It can even give you directions via Google Maps and if you want to know what the weather will be during an appointment (that’s well before the appointment) then you can see that.
This could be your Calendar app of choice. It’s free, a rarity in the iOS world for the good apps, and available in iTunes store now.
